Magnetization, magnetostriction, and elastic modulus measurements were made
on single crystal specimens of Tb1-xDyxZn. Easy axis magnetization rotatio
n as much as 26 degrees were observed in the (001) plane of Tb0.75Dy0.25Zn
below 33 K. From these measurements, values of the K-4/K-8 anisotropy ratio
s were calculated. No easy axis magnetization rotation was observed in the
x=0.6 and x=0.8 single crystals. Magnetostriction and modulus measurements
at 77 K in Tb0.4Dy0.6Zn showed a saturation magnetostriction of similar to
5x10(-3) and a maximum magnetomechanical coupling factor of 0.96. (C) 1999
