ANOMALOUS DELTA-E EFFECTS IN TBDYZN ALLOYS

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. (C) 1996 American Institute of Physics.
