Angular Response of Magnetostrictive Thin Films

الملخص EN

The magnetostrictions of the single TbFe layer and coupled Py/TbFe2 bilayers were measured by using laser deflectometry.

The dependences of the magntostriction performance on the driving magnetic field direction have been investigated.

The relationship studies between the saturation bending angle and torsion angle of the single layer with perpendicular anisotropy and coupled bilayers with in-plane uniaxial anisotropy have been conducted.

Interesting “jump” reflecting the spin dynamics is observed in the magnetostriction loops of the coupled bilayers.
