Abstract

Magnetomechanical coupling factor, piezomagnetic d-constant and magnetic permeability are reported as a function of magnetic field and applied stress for stress annealed Fe-Ga and Fe-Al alloys. Magnetic field dependences of the samples were measured as a function of the intrinsic saturation flux density (J_s), lowest order cubic anisotropy coefficient (K_cubic), uniaxial anisotropy lowest order coefficient (K_uniaxial) and saturation magnetostriction (lambda_sat).
