Anisotropy and Magnetoelastic Properties

2009
In this chapter, we discuss the local origins of the two measurable macroscopic effects that occur from interactions between the ionic magnetic moments and the lattices in which they reside: magnetocrystalline anisotropy and magnetostriction. In the preceding chapters, the focus has been on the molecular origin of the magnetic moments in crystal ...

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

Competition between shape anisotropy and magnetoelastic anisotropy in Ni nanowires electrodeposited within alumina templates

Physical Review B, 2006
Ni nanowires were deposited into nanoporous alumina by pulse electrodeposition. The temperature dependent magnetic properties are analyzed in detail and a maximum of coercivity and anisotropy field is observed around room temperature which cannot simply be explained by shape anisotropy.

Induced anisotropy and magnetoelastic properties in Fe-rich metallic glasses

Journal of Non-Crystalline Solids, 2001
Abstract Magnetoelastic measurements have been performed on metallic glasses of composition ( Fe 0.79 Co 0.21 ) 75+x Si 15−1.4x B 10+0.4x (x=0,2,4,6,8) by using the resonance–antiresonance method. Samples were obtained in the form of ribbons and annealed under applied field in such a way that a transverse and ...

Measuring the magnetoelastic anisotropy constant in manganite epitaxial thin films

Journal of Magnetism and Magnetic Materials, 2004
Abstract We present direct measurement and indirect determination of the irreducible magnetoelastic stress coefficient B1 performed in La2/3Ca1/3MnO3 epitaxial thin films grown on SrTiO3(0 0 1) and LaAlO3(0 0 1) substrates. The values obtained are, respectively, −13 and −16 MPa.

Transverse magnetic anisotropy of magnetoelastic origin induced in Co nanowires

Physica B: Condensed Matter, 2006
The magnetic properties of arrays of magnetic nanowires, prepared by electrodeposition in nanopores of alumina membranes, were investigated. The hysteresis loops were measured using a magnetic field applied both perpendicularly and parallel to the nanowire axes for temperatures between 4 and 300 K.

Effect of magnetoelastic anisotropy on properties of Finemet-type microwires

Journal of Alloys and Compounds, 2012
Abstract Magnetic properties and DSC peak near Curie temperature, TC, of amorphous and nanocrystalline microwires with different ratios ρ = d/D were studied. The investigated compositions were close to Finemet-type: Fe70.8Cu1Nb3.1Si14.5B10.6, Fe71.8Cu1Nb3.1Si15B9.1 and Fe73.8Cu1Nb3.1Si13B9.1.

Nonlinear magnetoelastic anisotropy in Cu/Ni/Cu/Si(001) films

Journal of Applied Physics, 1999
A spin-pair model including magnetoelastic terms to second order in strain is used to analyze the magnetic anisotropy of epitaxial Cu/Ni/Cu/Si(001) films. Two adjustable parameters are used to fit the magnetic anisotropy data taken by a torque magnetometer.

Magnetoelastic effects and magnetic anisotropy in amorphous Fe-P alloys

IEEE Transactions on Magnetics, 1984
The field dependences of elastic moduli were measured in electrodeposited amorphous Fe-P and Co-P tubes by resonance techniques at about 400 Hz and between 0.2 and 8 MHz. On account of magnetic anisotropies established during preparation (intrinsic anisotropy) and by field annealing, the magnetoelastic effects depended sensitively on the stress modes ...

Magnetocrystalline and magnetoelastic anisotropies in (110) bcc thin films and superlattices

Journal of Magnetism and Magnetic Materials, 1995
Abstract The magnetocrystalline and magnetoelastic anisotropy energies of bcc (110) thin films and superlattices are predicted from group theory and calculated within the framework of an extended pair model. The calculation shows the magnetocrystalline and magnetoelastic anisotropy energy per atom in a monolayer to be twice that of a surface layer ...
