Abstract

Magnetostrictive strains and magnetic induction have been measured as a function of applied DC field and pressure on the giant magnetostrictive material Tb_xDy_1-xFe_y ( x=0.3, 1.92⩽y⩽1.95). Dynamic measurements of the magnetomechanical coupling k₃₃ as a function of DC bias field and pressure have been obtained using a novel pressure rig. These results have provided data on how the properties of the materials required for optimal device operation change with operating conditions
