Law of the Approach to Magnetic Saturation

Law of the Approach to Magnetic Saturation
application/pdf The variations of a/H- and b/H^2- terms in the formula of 'Approaching Law' caused by deformation were investigated. The results were explained by Brown's theory. Comparing Brown's theory with Becker's, it was concluded that the origin of a/H-term lay in the correlation of magnetization with the stress around piled dislocations, and ...

Large Anomalous Nernst Effect in Disordered CoPt Thin Films for Planar Thermoelectric Sensing

Advanced Electronic Materials, EarlyView.
Disordered CoPt thin films exhibit a large anomalous Nernst effect with strong dependence on Pt concentration. The transverse thermoelectric response reaches 3.22 µV K−1 near equiatomic composition and an ANE sensitivity of 0.3 µm A−1. The results reveal that composition‐controlled microstructure in sputtered CoPt alloys provides an effective route for

Remarkable Electric Field‐Controlled Magnetism in La/Sm Co‐Substituted BiFeO3 Multiferroic Ceramics

Advanced Electronic Materials, EarlyView.
The remarkable electric field‐controlled magnetism (change of Mr reaches up to 62.7%) in La/Sm co‐substituted BiFeO3 ceramics, originating from the electric field‐induced phase transition of Pna21/R3c, is achieved by enhancing the dielectric strength. Moreover, the significant improvement in ferroelectricity is also determined after the electric field ...

Discovery of an Ideal HgO12 Icosahedron and Magnetodielectric Coupling in HgCu3Ti4O12

Advanced Electronic Materials, EarlyView.
HgCu3Ti4O12, an A‐site‐ordered quadruple perovskite with a perfectly regular HgO12 coordination, has been synthesized for the first time using high‐pressure methods. The material shows antiferromagnetic ordering at 31 K together with an intrinsic dielectric anomaly, implying possible magnetodielectric coupling.

Pyridine‐Isomerism‐Driven Spin Engineering at a COP‐Fe3O4 Interface for High‐Performance Oxygen Reduction Electrocatalysis

Advanced Energy Materials, EarlyView.
Strategically adjusting the pyridine nitrogen position in the polymer matrix (pyridine isomerism) intensifies its interaction with embedded Fe3O4 nanocrystals. This enhanced interaction induces a spin‐state transition in Fe from low‐spin to intermediate‐spin, accompanied by refined d‐orbital properties.
