Abstract

Using magnetic and magnetoelectric (ME) powder susceptibility measurements, the low temperature magnetic properties of antiferromagnetic UCrO4 and NdCrTiO5 have been studied. Their Néel temperatures TN are 44.5 and 20.5°K, respectively, the Cr3+ spin systems of both materials ordering cooperatively at TN. Below TN, the U5+ and Nd3+ moments are polarized due to their exchange interaction with the ordered Cr3+ spins. It is argued that, for both compounds, each of the two spin systems contributes to the ME susceptibilities. They are thus the first known ME materials possessing two distinct magnetic sublattices. The effective magnetic moments calculated from the magnetic susceptibilities are in good agreement with those previously reported by neutron diffraction studies.
