Abstract
The magnetic and magnetostrictive properties of the TbxDy1-x highly magnetostrictive alloys were measured in the region of large magnetostriction to anisotropy ratios ( x =0.5, 0.6, and 0.67). Magnetizations and magnetostrictions under compressive stresses up to 25 MPa and fields up to 2 kOe were compared to theoretical curves. Field dependences clearly display magnetization discontinuities and magnetic rotation regions. From these data and from corresponding elastic modulus measurements, permeabilities, piezomagnetic d -constants (d 33 ), and elastic compliances were calculated. For some values of stress and magnetic field, ΔE effects >10 and coupling factors (k 33) approach unity
