Abstract :
Magnetization, magnetostriction, and modulus measurements have been performed on single crystal specimens of the pseudobinary Tb0.5Dy0.5Zn. Non-principal axis easy magnetization directions were observed in the (001) plane at temperatures below 20 K. At all temperatures, [110] is the hard axis. At 2.2°K the anisotropy field is estimated to be 5.6 MA/m (70 kOe). Magnetostriction and modulus measurements at 77 K showed a saturation magnetostriction of ~5×10-3 and a modulus that varied from 10-60 MPa depending on field
