Effect of lattice strain on magnetism in epitaxial YCrO3 films

Materials Research Letters, 2022
The influence of lattice strain on magnetism is studied for perovskite rare-earth chromite, YCrO3 (YCO) thin films. A combined theoretical and experimental approach is used to demonstrate the correlation between lattice-strain and magnetic properties of ...

Equivalent Electrical Model of an Inductor Excited by a Triangular Current Including Saturation

Communications, 2020
A model for an equivalent electrical circuit designed for a ferrite (3C90) inductor usually used in power converters excited by a non-sinusoidal current appropriate for use in power electronics is proposed. This study, based on 3D finite element analysis,

Remarks on the Quantum Effects of Screw Dislocation Topology and Missing Magnetic Flux

Condensed Matter
We revisit the interaction between a point charge and an inhomogeneous magnetic field that yields the magnetic quantum dot system. This magnetic field is defined by filling the whole space, except for a region of radius r0.

A Theoretical Study of the Effects of Co-Doping Ions at K and Nb Sites on the Properties of KNbO₃ Nanoparticles

Nanomaterials
Using a microscopic model and Green’s function theory, we have investigated the co-doping effect on ferroelectric KNbO3 nanoparticles. Let us emphasize that while the doping with transition metal ions at the Nb site leads an increase in the ...
