摘要：
A survey of the subsolidus phase equilibria in the system Li2O-Nd2O3-Fe2O3 was made at subsolidus temperatures in the range 1000-1050 degrees C. A ternary phase was identified. The phase is centered on Li5Nd4FeO10, with a cubic lattice a = 11.9494 angstrom. The compound melts incongruently at 1105 degrees C. The magnetic susceptibility was measured in the temperature range 4-300 K. The compound is paramagnetic in the temperature range 150-300 K and follows the Curie-Weiss law. At about T-N = 10 K, a long-range magnetic ordering is observed. (C) 2005 Elsevier Ltd. All rights reserved.
