Magnetoelastic anisotropy of antiferromagnetic materials

Applied Physics Letters, 2019
Antiferromagnetic (AFM) materials are of great interest for spintronics. Here, we report the magnetoelastic anisotropy of an AFM IrMn thin film. An exchange-biased CoFeB/IrMn bilayer was used to obtain a single domain of the AFM thin film, and the magnetic moment arrangement of the AFM layer was deduced from the magnetic hysteresis loop of the pinned ...

Magnetic anisotropy and magnetoelastic properties of SmFe11Ti

Journal of Alloys and Compounds, 1997
Abstract We investigated the specific magnetization σ( T,B ), torque moments L ( ϕ ), Young's modulus E(T) , internal friction Q −1 ( T ), and magnetostriction λ( B ) of a single crystal and polycrystalline samples, of the SmFe 11 Ti compound, in the temperature region 77–700 K in magnetic fields up to 1.6 T. Below the Curie temperature ( T c =

Anisotropy of magnetoelastic phenomena in Lu2Fe17 intermetallics

Journal of Magnetism and Magnetic Materials, 2004
Abstract The anisotropy of magnetoelastic phenomena that accompanies changes of magnetic structures in the Lu2Fe17 intermetallics was studied under pressure. A huge anisotropy in compression ( d ln c/ d p≅2 d l n a/ d p) and thermal expansion ( d ln c/ d T≅−5 d ln a/ d T) of the Lu2Fe17 crystal lattice ...

Magnetoelastic anisotropy distribution in glass-coated microwires

Journal of Materials Research, 1996
Amorphous microwires, obtained by the glass-coated melt-spinning method having diameters in the range of micrometers, can exhibit perfectly square (single and large Barkhausen jump) or quasi-anhysteretic hysteresis loops, depending on the easy magnetization direction determined by the intrinsic magnetoelastic anisotropy.

Influence of the packing fraction and host matrix on the magnetoelastic anisotropy in Ni nanowire composite arrays

Journal of Applied Physics, 2013
The influence of the packing fraction on thermally induced magnetoelastic effects has been studied in Ni nanowires embedded in polycarbonate, poly(vinylidene difluoride), and alumina nanoporous membranes of different porosities for temperatures between ...

Anisotropy of magnetoelastic wave attenuation in (111) crystal plates with combined anisotropy

Technical Physics, 2002
The effect of dissipation on the propagation of magnetoacoustic waves in a cubic ferromagnet under the action of applied stress σ ∥ [111] is studied theoretically. When the ferromagnet is in one of two symmetric phases (M0 ∥ [111] or M0 ∥ [110]), the magnetoelastic waves weakly decay and may transform into modes of another type as the material ...

Magnetoelastic coupling induced magnetic anisotropy in Co2(Fe/Mn)Si thin films

Applied Physics Letters, 2014
We report the influence of in-plane strain on uniaxial magnetic anisotropy of Co-2(Fe/Mn)Si [CF(M)S] films grown on SrTiO3 (STO) and MgO by varying film thickness.

Influence of Magnetoelastic Anisotropy on Properties of Nanostructured Microwires

Advanced Materials Research, 2013
We studied the effect ofthe magnetoelastic ansitropy on properties of nanostructured glass-coated microwires with soft magnetic behaviour (Finemet-type microwires of Fe70.8Cu1Nb3.1Si14.5B10.6, Fe71.8Cu1Nb3.1Si15B9.1 and Fe73.8Cu1Nb3.1Si13B9.1 compositions) and with granular structure (Cu based Co-Cu microwires).

Exchange striction, the origin of polycrystalline magnetoelastic anisotropy

Physical Review B, 1981
It is analytically shown that the origin of the magnetoelastic anisotropy term $\ensuremath{\Delta}K$, previously established as specific of the polycrystalline state, is related to the product of the strong isotropic virtual "exchange stresses" due to the exchange striction by the anisotropic magnetostrictive deformation constrained by the neighboring

Magnetoelastic contribution to the interface anisotropy of Pd/Co metallic multilayers

Physical Review B, 1996
First-principles calculations of the magnetic anisotropy energies of Pd/Co metallic multilayers have been performed to investigate the effect of strain on the interface magnetic anisotropy. Also, to clarify the contribution of the interface to anisotropy, the anisotropy energies of an unsupported Co monolayer and bulk Co have been calculated. These two
