Subsolidus phase equilibria and the Li[sub]5Nd[sub]4FeO[sub]10 phase in the Li[sub]2O-Nd[sub]2O[sub]3-Fe[sub]2O[sub]3 system
Irena Ban, Mihael Drofenik, Danilo Suvorov, Darko Makovec, 2005, original scientific article

Abstract: A survey of the subsolidus phase equilibria in the system Li2O-Nd2O3-Fe2O3 wasmade at subsolidus temperatures in the range 1000-1050 °C. A ternary phase was identified. The phase is centered on Li5Nd4FeO10, with a cubic lattice a =11.9494 A. The compound melts incongruently at 1105 °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 TN = 10 K, a long-range magnetic ordering is observed.
