Summary: The corrosion behavior of material-type and process-type super-strength sucker rod steels in a high sulfide-containing solution was investigated in this study. The results showed that the material-type steel exhibited higher corrosion resistance compared to the process-type steel in a near neutral high sulfide environment. The corrosion processes of these steels were mainly controlled by the alloy elements they contained, which influenced the formation of corrosion product deposits and the difference in corrosion rates.

Summary: This study investigates the effect of Sm doping on the structural, dielectric, multiferroic, and electrical properties of GaFeO3. It is found that the unit cell volume increases with increasing Sm content, and irregular-shaped grains are uniformly distributed on the surface. Significant variations in the dielectric properties are observed with different Sm contents. Furthermore, the coexistence of ferroelectric and magnetic ordering is confirmed, and the remanent polarization and magnetization decrease with increasing Sm content.

Summary: This study investigates the influence of Fe-doping on the magnetic and transport properties of Co3Sn2S2, finding that Fe-doping suppresses magnetic order, increases electrical resistivity, contributes to the anomalous Hall effect, and causes the Kondo effect. Fe-doping also significantly reduces the magnetoresistance of Co3Sn2S2 and induces hysteresis behavior in the low magnetic field region.

Summary: The influence of doping with the 5d transition metal W has been studied in the quaternary (Mn,Fe)2(P,Si) based giant magnetocaloric compounds. It is found that W substitution can separately decrease the Curie temperature TC and retain the thermal hysteresis increment Thys at an almost constant level. Low-content W doping conserves the good magnetocaloric effect without an obvious degradation.

Summary: Electrons in solids adopt complex patterns of chemical bonding driven by energy gains and costs. We report a chemical pressure-driven transition in EuMn2P2 from proper Mn magnetic ordering to a Mn magnetic phase crossover, despite remaining an insulator at all temperatures. The absence of a Mn magnetic phase transition contrasts with other isoelectronic materials. Our results demonstrate the sensitivity of the band structure to magnetic order and imply the suppression of long-range Mn magnetic order by chemical pressure.

Summary: The electronic structure and ferroelectric-ferromagnetic coupling properties of Y-doped and vacancy-containing GaN-ZnO heterojunctions are systematically investigated. The magnetism in vacancy-containing systems is generated by the spin polarization of unpaired electrons induced by cationic vacancies, while in Y-doped systems, bound magnetic polarons are formed by the orbital hybridization of s-state and d-state electrons of Y-doped elements.

Summary: The elementary excitations spectrum of anisotropic frustrated antiferromagnets in the fan phase is discussed. It is found that the low-energy part of the spectrum consists of a gapless phason branch with linear dispersion and a gapped optical branch corresponding to the fan structure amplitude oscillations. In the high-energy part of the spectrum, the excitations are similar to the magnons of the fully polarized phase.

Summary: In this study, the departure frequency of vapor bubbles during boiling of ferrofluid in a horizontal magnetic field is experimentally investigated. 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.
