New High‐Tc Charge‐Transfer Multiferroicity in the Quasi‐2D Antiferromagnet CrSbS3

Advanced Science, EarlyView.
ABSTRACT Low‐dimensional magnets, particularly 2D systems, offer a rich platform for realizing unconventional multiferroic mechanisms, especially when multiple polarization channels coexist. In the quasi‐2D antiferromagnet CrSbS3, which crystallizes in the centrosymmetric orthorhombic space group Pnma and orders magnetically at TN ≈ 90 K, two ...

Magnetocaloric studies of the peak effect in Nb [PDF]

Physical Review B, 2007
We report a magnetocaloric study of the peak effect and Bragg glass transition in a Nb single crystal. The thermomagnetic effects due to vortex flow into and out of the sample are measured. The magnetocaloric signature of the peak effect anomaly is identified.

Sublattice‐Resolved Magnetoelastic Coupling and Opposing Pressure Responses in the Frustrated Magnetocaloric GdMn2O5

Advanced Science, EarlyView.
In GdMn2O5, sublattice‐resolved EXAFS and diffraction analysis reveal pronounced spin‐phonon coupling and an unexpected opposing pressure response: the Mn‐driven Néel temperature slightly decreases while the Gd‐sublattice ordering temperature rises under pressures up to 0.86 GPa.

Proximity-Enhanced Magnetocaloric Effect in Ferromagnetic Trilayers [PDF]

, 2022
The demagnetization and associated magnetocaloric effect in strong-weak-strong ferromagnetic trilayers, upon a reorientation of the strong ferromagnets from parallel to antiparallel magnetization, is simulated using atomistic spin dynamics.

Using a computationally driven screening to enhance magnetocaloric effect of metal monoborides

JPhys Energy, 2023
In most cases, substitution studies that aim to optimize magnetic properties are performed at the magnetic atomic site. However, in the case of MnB, magnetic substitutions at the Mn site significantly decrease the once promising magnetocaloric and ...

Specific heat and magnetocaloric effect in UNiGa [PDF]

Physica B: Condensed Matter, 1993
Abstract Temperature dependence of the specific heat was measured on a single crystal of UNiGa in magnetic fields. The value γ =40.9 mJ/mol K 2 does not change with the field-induced transition. The magnetic entropy is larger in the high-field (ferromagnetic) state (0.55× R In2) than in the AF ground state (0.50× R In2).

Combinatorial Survey of Structural Phase Distribution and Magnetism in Fe‐Ge‐Te Composition‐Spread Thin Film Libraries

Advanced Electronic Materials, EarlyView.
ABSTRACT Magnetic 2‐dimensional (2D) van der Waals (vdW) materials have garnered tremendous attention. The vdW ferromagnet Fe5Ge1Te2 has a Curie temperature Tc of ≈ 270 K, which is tailorable by tuning the stoichiometry and the Fe deficiency to reach room temperature.

Large Magnetocaloric Effect in a Ferromagnetically Coupled [Mn3Gd] Complex With a Spin Ground State of S = 11

Chemistry – A European Journal, EarlyView.
Systematic studies of a series of new 3d–4f tetranuclear complexes revealed that the ferromagnetically coupled [Mn3Gd] complex exhibits large magnetic entropy changes, especially at higher temperatures and under lower magnetic fields. ABSTRACT A series of 3d‐4f heterometallic tetranuclear complexes, (TEA)[Mn3Gd(L)3(NO3)4(CH3CN)2] ([Mn3Gd]), (TEA)[Mn3La(
