Magnetoelastic effects and random magnetic anisotropy in highly strained ultrathin Ni nanowires epitaxied in a SrTiO3 matrix

, 2020
International audienceWe analyze the magnetic anisotropy of Ni nanowires with diameters smaller than 5 nm. The nanowires are vertically epitaxied in a SrTiO 3 (001) matrix which generates huge tensile strains up to 3.6% along the nanowire axis.

Magnetic Anisotropy of FeAlSi Sputtered Films

, 1991
The FeAlSi film magnetic anisotropy has been studied in relation to the residual stress and crystalline orientation. Experiments show that the magnetic anisotropy behavior depends on the geometrical location of the substrate with the target during the ...

Switching the spin cycloid in BiFeO3 with an electric field

Nature Communications
Bismuth ferrite (BiFeO3) is a multiferroic material that exhibits both ferroelectricity and canted antiferromagnetism at room temperature, making it a unique candidate in the development of electric-field controllable magnetic devices.

Magnetic and magnetoelastic properties of a ferromagnetic single crystal with cubic symmetry

, 2017
A crystal hamiltonian is written from symmetry considerations, including magnetic and elastic contributions, first-order magnetoelastic coupling (magnetostriction) and second-order magnetoelastic coupling (isotropic and morphic effects).

Magnetostrictive properties of amorphous SmCo thin films with imprinted anisotropy

, 2014
We examine the magnetostriction in amorphous SmCo thin films with a composition in the range 4-27 at.% Sm. The magnetostriction increases significantly with increasing Sm content but is small compared to terbium-based ferromagnetic compounds, despite the
