Flexoelectric nanodomains in rare-earth iron garnet thin films under strain gradient

Communications Materials, 2021
Rare-earth iron garnets are ferrimagnetic insulators commercially known for their large magneto-optical effect. Here, strain-gradient engineering is used to induce flexoelectricity in Sm3Fe5O12 films, achieving simultaneous remanent dielectric ...

Influence of Magnetofossils on Paleointensity Estimations Inferred From Principal Component Analyses of First‐Order Reversal Curve Diagrams for Sediments From the Western Equatorial Pacific

Geochemistry, Geophysics, Geosystems, 2021
Relative abundance of magnetite originated from magnetotactic bacteria (magnetofossils) in sediments may influence relative paleointensity (RPI) estimations of the geomagnetic field, as some studies reported an inverse correlation between RPI and the ...

Large Anomalous Hall Effect, Non‐Vanishing Berry Curvature in (110) FeRh Antiferromagnet Films via Interface Strain

Advanced Science, EarlyView.
This study demonstrates a strain‐tunable anomalous Hall response in the (110)‐oriented FeRh thin film. First‐principles calculations reveal that strain‐induced symmetry lowering redistributes Berry curvature near the Fermi level via band shifts and avoided crossings.

Strain‐Assembled Crystalline SrRuO3 Microtube and Emergent Curvilinear Magnetism

Advanced Science, EarlyView.
The interfacial‐strain assembly based on planar nanomembranes presents a promising approach for constructing novel magnetic microstructures. By employing the perpendicular magnetic anisotropic SrRuO3 freestanding nanomembrane as a model system, we exploit the interfacial strain effect within the crystalline SrTiO3/SrRuO3 bilayer, and successfully ...

Shock demagnetization in an ambient magnetic field at the Dhala impact structure, India

Communications Earth & Environment
Impact-generated shock waves can modify the remanent magnetization preserved in target rocks, yet their effects remain poorly constrained. Here we examine how shock waves modify rock magnetization by analysing unshocked granitoids and diorites, and shock-
