The alloys series Tb{sub 1{minus}x}Dy{sub x}Zn, x {le} 0.6, has been shown to undergo easy-axis reorientations at low temperatures. In this paper results of magnetization on single crystal disks of Tb{sub 0.6}Dy{sub 0.4}Zn are reported. Maxima in the magnetization as much as 15{degree} from the <100> axes were found below T{sub R} {approx_equal} 20 K. Magnetostrictions of 5 {times} 10{sup {minus}3} were measured at 77 K on single crystal rods. Magnetization versus field curves under a series of compressive stresses have verified the highly magnetoelastic nature of this alloy. The non-principal magnetization orientations are discussed on a phenomenological model which includes an eighth-order anisotropy term.
