Summary: This study investigates the impact of spin-orbit coupling (SOC) on the electronic and magnetic properties of Mn1.5PtSn compound using density functional theory. Regardless of SOC, ferrimagnetic configuration is found to be more stable at the ground state compared to ferromagnetic and antiferromagnetic configurations. The SOC affects the ground state energy of the compounds, and various analysis methods provide insights into the magnetic and electronic properties of the system. The stable ferrimagnetic configuration shows high spin polarization and low magnetocrystalline anisotropy energy, making it suitable for spin-transfer-torque-based device applications like magnetic recording heads.

Summary: Using ab initio calculation, the structural, electronic and magnetic properties of Co2Nb1+xZ1-x (x = 0, 0.25, 0.50) were systematically investigated. It was found that except for Co2NbSn, all compositions did not exhibit martensitic structural transition, which was associated with Jahn-Teller distortion of Co 3d orbitals near the Fermi level. The density of states for Co2NbSn in both tetragonal and 4 O orthorhombic structures were examined. Co2NbSn showed metallic character, while Co2NbGa, Co2NbIn, and off-stoichiometric alloys were predicted to have partial half-metallic character. Nb doping increased the total magnetic moment due to increased Nb-Co hybridization of d orbitals.

Summary: The phase stability of Ti2MnAl Heusler compound was investigated using first-principles calculations. The formation mechanisms of non-magnetic Ti2MnAl in Cu2MnAl-type structure and spin gapless semiconductor in Ti2MnAl with Hg2CuTi-type structure were revealed. It was found that the kinetic arrest of atomic diffusion during sample preparation resulted in the metastable spin gapless semiconductor in Ti2MnAl film sample. The study suggests that interatomic orbital hybridization is crucial for the atomic configuration and phase stability in Ti2MnAl, and it can be controlled by careful control of the kinetic diffusion process.

Summary: This study investigates the magnetic and electronic properties of Co2ZrSn and Co2HfSn Heusler alloys through a combination of experimental and ab-initio investigations. The experimental results indicate that both alloys exhibit different ferromagnetic properties at different temperatures, transitioning from localized ferromagnetism to weak itinerant ferromagnetism. Ab-initio calculations show the presence of a half-metallic band gap in both compounds. The magnetic moments and band gap width are found to depend on the cell parameters.

Summary: In this study, the structural, magnetic, electronic, and thermoelectrical properties of full Heusler compounds CoXZeGe (X = Rh, Ru) were investigated for the first time. The investigation utilized both the Generalized Gradient Approximation (GGA) and the Modified Becke-Johnson (mBJ) approximation. The compounds crystallized in the Cu2MnAl prototype and exhibited a ferromagnetic phase. The calculated magnetic moments were determined to be 1 mu(B) for CoRuZeGe and 2 mu(B) for CoRhZeGe. Furthermore, the compounds displayed a half metallic behavior with full spin polarization, making them excellent candidates for spintronic applications. The thermoelectric properties, including the Seebeck coefficient (S), electronic thermal conductivity (kappa(e)/tau), power factor, and figure of merit (ZT), were also extensively studied and discussed. Overall, these investigated compounds were identified as potential materials for high technological applications.

Summary: In this study, the structural parameters, electronic band structures, and thermoelectric properties of A(2)BCl(6) materials (where A = Cs, K and B = Se, Sn, Ta, Te, Ti, W, Zr, Mn, Mo, Os, Pd, Pt, Re, Ru, Tc, W) at zero pressure and elevated temperatures were investigated using density-functional theory and the CASTEP code. The calculated results generally agreed with the available literature, and in some cases, predictions were made. The calculated lattice parameters were found to have an error of less than 3% compared to experimental data. It was observed that Cs2BCl6(B=Se, Sn, Te, Ti, Zr) and K2BCl6(B=Pd, Pt, Sn) materials were semiconductors with band gaps ranging from 3.14 to 5.00 eV. Cs2BCl6(B=Ta, W) and K2BCl6(B=Ta, W, Mn, Mo, Os, Re, Ru, Ta, Tc) compounds exhibited metallic properties, indicating conductivity. The thermoelectric properties such as thermal conductivity, electrical conductivity, and Seebeck coefficient were also calculated using the BoltzTrap code. The results suggested that these materials could be suitable candidates for thermoelectric and optoelectronic applications.

Two methods, visual and inductive, are used to measure the frequency of bubble departure. The results show that the bubble departure frequency can decrease with increasing magnetic field strength and increase with increasing temperature of the heat-emitting surface. A linear stability analysis is conducted to analyze the influence of the magnetic field on the frequency of bubble formation during ferrofluid boiling.

Summary: This study investigates the thermodynamic quantities, such as entropy, specific heat, and magnetic susceptibility, in the next-nearest-neighbors Heisenberg model on a honeycomb-kagome lattice. The linear spin-wave approach is applied to obtain the temperature-dependent behavior of these quantities. Additionally, the entanglement negativity, a quantifier of quantum entanglement, and the spin Hall conductivity are also studied. The results show that all the thermodynamic quantities, as well as the entanglement negativity and spin Hall conductivity, exhibit an increasing trend with temperature. Furthermore, it is found that all the analyzed quantities approach zero in the low-temperature limit, consistent with experimental observations.
