摘要：
Magnetization measurements of a La1/3Nd1/3Ca1/3MnO3 perovskite at magnetic field up to 6 T have revealed an anomalous behaviour - above 130 K the material exhibits a loop displacement about a field of 2 T. We assume that this is the result of an exchange interaction between ferromagnetic and antiferromagnetic phases in a magnetically inhomogeneous compound. At about 115 K a transition from a semiconducting to a metallic-like state has been observed. (C) 1999 Elsevier Science B.V. All rights reserved.
