Magnetic Structure of the High‐TN Antiferromagnet La0.5Sr3.5Fe3O7.5F2.6: A Temperature‐Dependent Mößbauer Spectroscopy and Neutron Diffraction Study

Zeitschrift für anorganische und allgemeine Chemie, EarlyView.
La0.5Sr3.5Fe3O7.5F2.6, a rare n = 3 Ruddlesden–Popper oxyfluoride, exhibits robust antiferromagnetism across a wide temperature range from 1.7 to 470 K. Temperature‐dependent neutron diffraction reveals an orthorhombic nuclear and a monoclinic magnetic structure, while Mößbauer spectroscopy shows persistent short‐range magnetic order up to 525 K.

Huge magnetoresistance in magnetic nanocontacts

, 2020
The quasiclassical theory of a nanosize point contacts (PC) between two ferromagnets is developed. The maximum available magnetoresistance in PC is calculated for ballistic and diffusive transport at the area of a contact, in the ballistic regime, the ...

Omnipolar Magnetic Field Detection by Superlattice‐Based Hall Sensor

Advanced Functional Materials, Volume 36, Issue 81, 8 October 2026.
Magnetic‐field‐induced electronic switching is demonstrated in unit‐cell‐engineered La0.7Sr0.3MnO3–BiFeO3 superlattices. Distinct substrate terminations modify magnetic and transport properties. Hall resistance measurements show omnipolar, hysteretic anomalous Hall switching above the Curie temperature, arising from Fe─Mn interfacial exchange, enabling

Computational and Experimental Thermoelectric Properties of YCuSb2

Advanced Sustainable Systems, Volume 10, Issue 10, October 2026.
The thermoelectric properties of the topological material YCuSb2 and its Te‐doped derivatives are investigated through a combination of experimental and computational methods. The materials exhibit low lattice thermal conductivity and electrical resistivity due to high carrier concentrations.
