Abstract

PURPOSE: To obtain a compound having a hexagonal system laminar structure represented by YbFeCoO4 by mixing Yb, Fe and Co or oxides thereof in a specified atomic ratio and heating the mixture at a proper temp. in a specified atmosphere.
CONSTITUTION: Yb, Yb2O3 or a compound decomposable into Yb2O3 by heating is mixed with metallic iron, Fe2O3 or a compound decomposable into Fe2O3 by heating and Co, CoO or a compound forming CoO by heating in the form of powder so as to make the atomic ratio among Yb, Fe and Co 1:1:1. This mixture is heated at ≥1,000°C in the air, an oxidizing atmosphere or a reducing atmosphere to such a degree that Fe and Co are not reduced from the tervalent ionic state and the bivalent ionic state, respectively, and after finishing the reaction, the reaction product is rapidly cooled. By this method a black YbFeCoO4 compound having a hexagonal system laminar structure is obtd. This compound is useful as a magnetic material, a semiconductor material and a catalyst.
