Abstract
We have used Mössbauer‐effect measurements of the hyperfine (hf) interaction in Eu metal to study the behavior of its sublattice magnetization just below the Néel temperature. From about 0.9≤T/Tc≤0.99, the hf field is accurately proportional to (1−T/Tc)β with β=0.20, but at 0.99Tc, the hf field falls from 0.4 of saturation to zero. This can be explained by the existence of a first‐order transition coincident with the magnetic ordering.This publication has 10 references indexed in Scilit:
