摘要：

The magnetic and transport properties of La1/3Nd1/3Ba1/3MnO3 with the colossal magnetoresistant (CMR) effect were studied by using SQUID. The irreversible curve for magnetizing intensity vs. temperature in an applied magnetic field of 13 Oe indicates that the spins of electrons are frozen, and therefore spin-glass state is probably formed below the Curie temperature. This fact implied that La1/3Nd1/3Ba1/3MnO3 is mictomagnetic, that is, ferromagnetism and antiferromagnetism co-exist in this kind of material. (C) 2002 Elsevier Science B.V. All rights reserved.
