Magnetic and magnetoelastic properties of single crystal Tb/sub 0.5/Dy/sub 0.5/Zn

Magnetization, magnetostriction, and modulus measurements have been performed on single crystal specimens of the pseudobinary Tb/sub 0.5/Dy/sub 0.5/Zn. 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/spl deg/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 /spl sim/5/spl times/10/sup -3/ and a modulus that varied from 10-60 MPa depending on field.
