We report the detailed investigation of the magnetic, transport, and magnetocaloric effects of GdS- bSe by magnetic susceptibility χ(T ), isothermal magnetization M (H), resistivity ρ(T, H), and heat capacity Cp(T ) measurements, crystallizing in the ZrSiS-type tetragonal crystal system with space group P 4/nmm. Temperature-dependent magnetic susceptibility measurements revealed long-range antiferromagnetic ordering with two additional magnetic anomalies below N´eel temperature (TN ≈ 8.6 K), corroborated through magnetocaloric and specific heat studies.

PbOCu(SeO)(NO)(OH) was synthesized by means of a replacement of (OH) groups for F ions of PbOCu(SeO)(NO)F, showing a transformation of kagomé and breathing kagomé lattices. Such a replacement did not change their intralayer ferromagnetic interactions and interlayer antiferromagnetic (AFM) interactions but slightly affected the Néel temperature and critical field, where PbOCu(SeO)(NO)(OH) possesses an AFM ordering at = 29.3 K, and a field-induced metamagnetic transition can occur at 2 K while a critical magnetic field of 1.

Article Synopsis
- The study synthesizes nanocrystalline samples of NixFe1-xCo2O4 at varying nickel concentrations via co-precipitation and annealing at 900 °C, revealing different crystallization phases and decreased particle size with more nickel substitution.
- Magnetic properties were analyzed, showing metamagnetic transitions in certain samples and dynamic susceptibility dependent on both nickel content and temperature, indicating complex magnetic states like spin-glass freezing.
- First principles density functional theory calculates suggest these materials exhibit ferrimagnetic and insulating behaviors, with potential applications in spintronics due to their distinctive electronic structures and spin-dependent characteristics.

We perform a numerical study of the kinetic Blume-Capel (BC) model to find if it exhibits the metamagnetic anomalies previously observed in the kinetic Ising model for supercritical periods [P. Riego et al., Phys.

In this paper, we propose to solve the issues of long-range or next-neighbor interactions by introducing randomness. This approach is applied to the square lattice Ising model. The Monte Carlo method with the Metropolis algorithm is utilized to calculate the critical temperature T_{C}^{*} under equilibrium thermodynamic phase transition conditions and to investigate the characterization of randomness in terms of magnetization.
