The temperature dependence of Young's modulus has been measured for a
series of Tb1-xDyxZn pseudobinary compounds with x ranging from 0 to 1
. From the sharp dips in the modulus vs temperature data, the reorient
ation transition temperatures have been determined, and the magnetic p
hase diagram deduced. Magnetization measurements taken on the same sam
ples show less pronounced features at the corresponding temperatures.
