Magnetoelectric coupling at the EuO/BaTiO3 interface

Applied Physics Letters, 2013
Magnetization modulation by ferroelectric polarization switching is reported for the ferromagnetic-ferroelectric EuO/BaTiO3 heterostructure. The value of the magnetization critical exponent β is consistent with the expected Heisenberg-like ferromagnetism of EuO and reported Curie temperature.

Machine Learning Approach to Characterize Ferromagnetic La0.7Sr0.3MnO3 Thin Films via Featurization of Surface Morphology

Advanced Science, EarlyView.
A machine‐learning approach is presented to characterize ferromagnetic LSMO thin films by featurizing their surface morphology. Through an ensemble model, the non‐linear correlations between surface morphology and the electric/magnetic properties of LSMO thin films are successfully captured.

Strain-mediated magnetoelectric coupling in magnetostrictive/piezoelectric heterostructures and resulting high frequency effects

, 2011
Magnetoelectric coupling terms are derived in piezoelectric/magnetostrictive (multiferroic) thin film heterostructures using Landau-Ginzburg free energy expansions in terms of strain and by considering strain boundary conditions between the two materials.

Spontaneous Strain‐Spin Transition Coupling Molecular Crystal with Thermal Magnetic Memory Effect, Anisotropic High‐κ and Switchable Dielectric Permittivity

Advanced Science, EarlyView.
A radical salt undergoes a paraelastic‐ferroelastic phase transition, which is coupled with spin‐Peierls transition, resulting in it integrating self‐strain, spin bistability, switchable dielectric and high‐ properties. Abstract Materials that exhibit controllable changes in electrical, magnetic, or spontaneous strain properties, particularly those ...

Logarithmic Helical Design for Reversed Magnetic Field in Magnetoelastic Soft Matters with Giant Current Outputs

Advanced Science, EarlyView.
According to literatures, magnetoelastic soft materials have achieved a maximum magnetic flux change of 80%, making it difficult to enhance the magnetic flux change. To address this, this manuscript proposed a reversed magnetic field strategy in conjunction with logarithmic helical design and magnetoelastic deformation.

Quantum Geometric Engineering of Dual Hall Effects in 2D Antiferromagnetic Bilayers via Interlayer Magnetic Coupling

Advanced Science, EarlyView.
Precise tuning of interlayer magnetic coupling in two‐dimensional bilayers enables control over altermagnetic and PT‐symmetric antiferromagnetic phases. This dual‐phase platform yields two intrinsic Hall responses: a Berry curvature–driven linear anomalous Hall effect and a quantum metric–induced second‐order nonlinear anomalous Hall effect ...
