Abstract
Measurements of the Néel and Curie temperatures of the alloy system TbxY1−x have been made from 5 to 90 kbar by an ac method in which the sample forms the core of a small transformer. The results are compared with similar measurements on the elements Gd, Tb, Dy, and Ho. In the alloy Tb0.95Y0.05 the temperature range over which the spiral structure exists (TN−Tc) increases slightly with increasing pressure. For alloys with more than 70% Tb, a transition ocurs at high pressure which by analogy to pure Tb is from the hcp to the Sm‐type structure. No ferromagnetism is observed in the Sm structure above 77°K. The percent change in TN at 30 kbar varies smoothly with concentration from 14% in Tb to a constant value of 7% below the 70% Tb alloy. This variation implies that the relation TN∝c⅔, where c is the concentration of Tb, does not hold at high pressures.This publication has 4 references indexed in Scilit:
