Abstract

The energy distributions of neutrons scattered by Co₃O₄ in its paramagnetic state have been measured by means of a time‐of‐flight technique. In this normal spinel with only A‐A interactions, the J_AA exchange integral has been derived from the second moment of these energy distributions. The result, J_AA/k_B = (7.27 ± 0.25) K, has been compared with values deduced from an analysis of the macroscopic magnetic data.
