Magnetization, magnetostriction, and modulus measurements have been pe
rformed on single crystal specimens of the pseudobinary Tb0.5Dy0.5Zn N
on-principal axis easy magnetization directions were observed in the (
001) plane at temperatures below 20 K, At all temperatures, [110] is t
he hard axis, At 2.2 degrees 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 similar to 5 x 10(-3) and a mo
dulus that varied from 10 - 60 MPa depending on field.
