Summary: Five mononuclear compounds were synthesized by combining cyclopentadiene, β-diketonate, tripyrazoylborate ligands, and dysprosium ion. Magnetic studies revealed that compounds 1Dy and 3Dy exhibited typical butterfly-type hysteresis, while compounds 1Dy-4Dy showed magnetic relaxation governed by the Orbach and Raman processes. Compound 3Dy showed a two-step magnetic relaxation attributed to the static disordering of the coordinated THF molecule. Magnetic anisotropy analysis indicated that the strength of interactions between Dy III and surrounding ligands determined the orientation of the magnetic easy axis.

Summary: Single-molecule magnets (SMMs) are attracting attention for their potential applications in high-density information storage and spintronic devices. Organic ligands and inorganic polyoxometalates (POMs) have been used to achieve high-performance SMMs. POMs offer advantages such as excluding dipole-dipole coupling and providing rigid frameworks for surface deposition and device applications. This review systematically summarizes the research progress and design strategies for POM-based SMMs, as well as the multifunctional properties for future application devices.

Summary: Single-molecule magnets (SMMs) with slow magnetization relaxation and purely molecular hysteresis are promising for information storage, spintronics, and quantum computing. Improving the blocking temperature (T-B) and effective relaxation barrier (U-eff) is crucial for their application. Multidisciplinary research has achieved SMMs with a U-eff up to 2,000 K and a T-B in the liquid nitrogen region. Enhancing the uniaxiality of magnetic anisotropy is critical for high-performance SMMs.

Summary: This study theoretically predicts that the emitted light from the plasmon mode in an STM single molecular junction can be squeezed with reduced quantum fluctuations under external laser drive. By selectively exciting energy levels, the squeezed plasmon can exhibit sub-or superPoissonian statistical properties. It is also demonstrated that the molecular excitonic mode can be squeezed simultaneously.

Summary: A series of four new Dy-12 dodecanuclear clusters based on azobenzene derivative ligands of salicylic acid have been synthesized and characterized. The formation of similar metallic cluster nodes in all obtained clusters has been revealed. Different porous 3D molecular networks and grids have been observed in different compounds. Three of the clusters exhibit a slow magnetic relaxation effect and one compound shows a decrease in the magnetic anisotropy energy barrier after UV irradiation, indicating the potential control over magnetic properties by external stimulus.

Summary: The crystal-field symmetry of lanthanide ions is crucial in suppressing quantum tunneling of magnetization in single-molecule magnets (SMMs). However, the design and modulation of high-performance SMMs remain challenging due to the geometric symmetry of the coordination sphere. This study reports two dysprosium single-ion magnets with pentagonal bipyramid geometry and investigates the magneto-structural relationships based on charge distribution. By modulating the crystal field, the charge-distribution symmetry can be chemically tailored, leading to the significant suppression of quantum tunneling and enhancement of reversal barrier in SMMs.

Summary: The effects of pressure (0-20 GPa) on the magnetic and structural properties of Fe3GeTe2 are investigated. It is found that ferromagnetic ordering is suppressed and a paramagnetic ground state emerges under pressure exceeding a critical value of P-PM ~ 15 GPa. An anomalous pressure dependence of structural parameters and vibrational modes is observed at P-C ~ 7 GPa, which is attributed to an isostructural phase transformation. Density functional theory calculations support these experimental findings. This study highlights the importance of pressure in driving magnetic quantum criticality in layered vdW magnetic systems.

Summary: A theoretical method considering the anisotropy of the internal magnetic field was proposed to predict the rate of quantum tunneling of magnetization in Kramers single-ion magnets. The method's predictions were consistent with previous theoretical results and indicated the importance of including the anisotropy of B-int for accurate description of QTM. The dependence of QTM rate on various parameters was analyzed, with some parameters showing linear dependence while others showing quadratic dependence.

Summary: A new series of homoleptic Ni(I) bis-N-heterocyclic carbene complexes with different torsion angles between the ligands have been reported. The complexes exhibit a strongly anisotropic g-tensor and the first excited state energy ranges from 270 to 650 cm(-1). The magnetic relaxation is dominated by Raman and direct processes, and the temperature dependence of the relaxation does not correlate with the torsion angle.

Summary: Phosphate ester bonds are stable in nature and can be isolated using a combination of phosphoryl and calix[4]arene moieties. In this study, hydrolyzed phosphoryl-calix[4]arene ligands were formed through Ln(III)-mediated P-OEt bond cleavage in L-PO. The resulting Ln(III) species were trapped as dimers, and the Dy derivative exhibited slow magnetization relaxation. This strategy can be further applied to create a broader range of hydrolyzed platforms that mimic nuclease enzymes.

Summary: This paper presents a study on coherent dynamic nuclear polarization (DNP) using frequency swept pulses at 94 GHz to optimize the polarization transfer efficiency. An enhancement of approximately 496 was observed using 10 mM trityl-OX063 as the polarizing agent in a standard 6:3:1 d (8)-glycerol/D2O/H2O glassing matrix at 70 K, which is currently the largest reported DNP enhancement at this microwave frequency and temperature. Furthermore, the frequency swept pulses enhance the nuclear magnetic resonance (NMR) signal and reduce the recycle delay, accelerating the NMR signal acquisition.

The magnetic properties of 1 show weak antiferromagnetic interactions between GdIII ions, resulting in a record magnetocaloric effect at low magnetic fields and temperatures. The magnetic entropy change reaches -Delta Sm= 29.3 J kg-1 K-1 for full demagnetization from B = 1 T at T = 0.5 K.

Summary: The reaction of 2,2'-bis-p-Bu-t-calix[4]arene (H8L) with Cu(NO3) (2)center dot 3H(2)O and N-methyldiethanolamine (MedeaH(2)) in a basic dmf/MeOH mixture results in the formation of [Cu-II (16)(L)(2)(Me-dea)(4)(mu(4)-NO3)(2)(mu-OH)(4)(dmf)(3.5)(MeOH)(0.5)(H2O)(2)] (H6L)center dot 16dmf center dot 4H(2)O (4). The metallic skeleton of the compound consists of a tetracapped square prism, [Cu-12], with Cu-II ions housed in the calix[4]arene polyphenolic pockets. Magnetic measurements show antiferromagnetic exchange interactions and a ground state of S = 1, while EPR indicates a large zero-field splitting.

Summary: Ultrafast transient absorption spectra were recorded for [MnIII(cyclam)(H2O)(OTf)][OTf]2 in water to study the equatorial expansion restriction after dxy-dz2 electronic transition. Strong oscillations in the excited state absorption signal were attributed to an excited state wavepacket. The structural rigidity of the cyclam ligand causes a complex reaction coordinate with certain frequencies, leading to a shorter compressed-state lifetime. Complementary density functional theory quantum chemistry calculations support the successful restriction of the wavepacket motion.

Summary: Equimolar amounts of MnBr2 center dot 4H(2)O and HL1 react in a basic MeCN solution to produce [Mn-4(II)(L-1)(4)Br-4(H2O)(4)] (1), with a [Mn-4(II)] tetrahedral metallic skeleton and a [Mn-4(II)(mu(3)-O)(4)] cubane cluster core. Replacement of MnBr2 center dot 4H(2)O with Mn(O2CMe)(2)center dot 4H(2)O yields [(Mn2Mn12O2)-Mn-III-O-II(L-1)(4)(OAc)(22)] (2), which can be described as a series of edge-sharing [Mn-4] tetrahedra that form a linear array with a corkscrew-like twist in each [Mn-2] pair. Reaction of the triangle [(Mn3O)-O-III(OAc)(6)(py)(3)](ClO4) instead of a Mn-II salt results in [(Mn14Mn4O14)-Mn-III-O-I(L-1)(4)(HL1)(2)(OAc)(18)(H2O)(2)] (3), featuring three vertex-sharing [Mn-4(III)] butterflies flanked by a [Mn-4(III)] cubane and a [(Mn2Mn2II)-Mn-III] tetrahedron. Magnetic measurements of 1-3 indicate antiferromagnetic exchange interactions, with a diamagnetic ground state for [Mn-4] (1) and Single-Molecule Magnet (SMM) behavior with U-eff = 22 K for [Mn-18] (3).
