${\mathrm{Fe}}_{2}({\mathrm{Mo}\mathrm{O}}_{4}{)}_{3}$ is a well-established L-type ferrimagnetic (L-FIM) material with field-induced magnetic ordering (${T}_{\mathrm{N}2}$) and multiferroic properties below ${T}_{\mathrm{N}1}$ (around 12 K). In this study, we investigate the of through temperature- field-dependent ac dc susceptibility $\ensuremath{\chi}(T)$ measurements. Isothermal magnetization data reveal an additional metamagnetic transition (${H}_{\mathrm{C}2}$) beyond existing boundary...
In the present report, we examine a monoclinic crystal structure sample of Sm2CoMnO6 (SCMO) with space group P21/n, synthesized in polycrystalline single-phase form by solid-state reaction process. X-ray photoelectron spectroscopy study revealed presence mixed valence states for Co (2+ & 3+) and Mn (4+ 3+). M(T) data exhibits an inhomogeneous magnetic state ferromagnetic ordering at TC ~128 K due to super-exchange interactions Co2+-O2--Mn4+ antiferromagnetic-like spin correlations T< 50 K,...
In this report, we have investigated the detailed magnetodielectric properties associated with spin-phonon coupling in BaGdFeO4 polycrystalline compound. The room temperature synchrotron X-ray diffraction study confirms orthorhombic crystal structure a space group of Pnma. DC magnetization measurements indicate complex magnetic behavior multiple transitions at TN1 = 62 K and TN2 31 K. field-dependent study, field-induced metamagnetic their dependence been attributed to competing interactions...

ABSTRACTIn the family of Re 2 CoMnO 6 (Re= rare-earth) cobaltite-double perovskites, in contrast to parent La compound, Gd exhibits multiple magnetic transitions; ferromagnetic (FM) ordering, T C ~112 K followed by AFM transition, N ~47 K, spins ordering for T<10 and largeisothermal entropy changes. A study DC field-superimposed AC susceptibility measurements revealed field-induced glassy behavior below enhancement FM correlations above . From analysis Almeida-Thouless dynamical power-law...
In this study, we performed a detailed analysis of the magnetoelectric properties polycrystalline BaHoFeO4 system. Rietveld refinement synchrotron x-ray powder diffraction pattern (SXRD) with space group Pnma confirmed that orthorhombic crystal structure was preserved down to lowest temperature (T) = 15 K. The DC magnetization indicated complex magnetic behavior multiple transitions at TN1 49 K, TN2 36 and TN3 7 interplay 3d 4f sublattices, competing interactions two different Fe -sites can...
