Summary: In the YIG|Pt system, we observed an increase in the spin Seebeck effect as temperature decreased, contrary to the behavior observed in electrical measurements. By analyzing the different contributions, we isolated the temperature dependence of the spin-mixing conductance and observed features correlated with the magnon spectrum bands in YIG.

Summary: We report the presence of a La2CuO4-like interlayer antiferromagnetic order in Sr2IrO4 films, and find that the crystal symmetry of Sr2IrO4 changes from tetragonal to orthorhombic in the epitaxial heterostructures of Sr2IrO4/Ca3Ru2O7, guiding the Ir 5d J(eff) = 1/2 pseudospin moment parallel to the elongated b axis via magnetic anisotropy.

Summary: The rare-earth monopnictide compounds have attracted considerable attention in condensed matter physics due to their correlation between magnetism, crystallographic structure, and transport. This study reports experimental observations of multiple metamagnetic transitions and magnetic structures in DyBi single crystals induced by high magnetic fields. The results reveal anisotropic magnetism and the existence of multiple phases, suggesting complex competition and balance in the system. The critical behavior analysis and comprehensive magnetic phase diagrams provide insights into the nature of magnetic interaction and the tricritical phenomenon in this system.

Summary: The spin-triplet superconductor UTe2 exhibits two superconducting phases under pressure, with zero resistance persisting up to 45 T. The high-field-induced superconducting phase is completely decoupled from the first-order field-polarized phase transition, indicating superconductivity boosted by a different pairing mechanism.

Summary: The Faraday effect is a phenomenon in which the polarization direction of light is changed when passing through a transparent material with a magnetic field. High Verdet constant magneto-optical materials have a wide range of applications, and recent research has focused on organic materials with higher Verdet constants.

Summary: The limitations of the two-particle self-consistent approach (TPSC) are addressed in this paper, and improved approaches, TPSC+ and TPSC+SFM, are proposed. The study shows that these improved methods are valid in the renormalized classical regime of the two-dimensional Hubbard model and recover certain criteria. However, the TPSC+ approach still violates the f-sum rule and conservation laws, which are solved within the TPSC+SFM framework.

Summary: Research has discovered that MnBi4Te7 is a topological insulator with quantum anomalous Hall effect and axion insulator phase. Through scanning tunneling spectroscopy, it has been observed that there is an electronic state at the edge of the magnetic MnBi2Te4 layer at 4.5 K, but not in the nonmagnetic Bi2Te3 layer. As the temperature increases, the edge state disappears, while the state induced by point defects persists.

Summary: GYAGG:Tb (Ce) scintillators were studied under intense 150 keV electron beam excitation. The Ce-doped material did not show saturation, while a moderate 30% drop of yield was observed in the Tb-doped sample at the highest excitation beam intensity. This provides a way to utilize Tb-doped scintillators for indirect beta-voltaic batteries.

Summary: The paper introduces improved versions of the two-particle self-consistent approach (TPSC+ and TPSC+SFM) and demonstrates their applicability in the two-dimensional Hubbard model. These improved methods address the limitations of the original TPSC approach and satisfy important theorems and principles. The paper also discusses the limitations of the TPSC+ approach and provides a solution within the TPSC+SFM framework.

Summary: Long-range magnetic order was observed in real icosahedral quasicrystals, with ferromagnetic transitions and appearance of magnetic Bragg peaks. Substitution of doping elements still retained ferromagnetic behavior. These findings contribute to further investigation of exotic magnetic orders on real quasiperiodic lattices with unprecedented highest global symmetry.

Summary: The study discovered a novel quasiparticle excitation in spin ice called a magnetic monopole, characterized by a single scaling form in the ac frequency dependent magnetic susceptibility of 2D spin ice. This behavior can be explained by the dynamical scaling law for 2D Coulomb gas systems and is a common feature among various models such as 2D superconductors, 2D superfluids, classical XY magnets, and dynamics of melting of Wigner crystals.

Summary: The magnetic structure of the sawtooth-chain antiferromagnet Fe2Se2O7 was investigated through magnetization measurements, neutron diffraction experiments, and Mossbauer spectra analysis, revealing a nearly collinear antiferromagnetic structure with magnetic moments aligned along the b-axis. The derived magnon dispersion relation suggests the possible flat band nature of magnons.

Summary: The magnetic properties of the antiferromagnet ZnxCu2-xV2O7 (ZnCVO) were thoroughly investigated. The study found similarities between ZnCVO and β-Cu2V2O7 (β-CVO) in terms of crystal structure and macroscopic magnetic properties. The spin network of ZnCVO was found to be better described by an anisotropic 2D spin network, different from the predicted 2D honeycomb structure.

Summary: The spin dynamics of the spin-1/2 kagome-lattice antiferromagnet Cs2Cu3SnF12 were investigated using high-resolution, time-of-flight inelastic neutron scattering. The results showed the presence of a flat mode and a low-energy dispersive mode, which can be described by the linear spin-wave theory. However, three weakly dispersive modes between 9 and 14 meV could not be explained by the theory and were suggested to be attributed to two-spinon bound states.
