PURPOSE:To obtain a novel compound useful as magnetic, semiconductor and catalyst materials, by blending respective metals or oxides of Tm, Fe and Zn and heating the resultant blend in a specific oxidizing or reducing atmosphere. CONSTITUTION:Metallic thulium, thulium oxide or a compound decomposable into the thulium oxide by heating is blended with metallic iron, iron oxide or a compound decomposable into the iron oxide by heating and metallic zinc, zinc oxide or a compound decomposable into the zinc oxide by heating at 1:1:9 atomic ratio of Tm;Fe:Zn. The resultant blend is then heated at >=650 deg.C temperature in the air. an oxidizing or reducing atmosphere in which the Tm and Fe are not respectively reduced from the trivalent ionic state and Zn is not reduced from the bivalent ionic state to afford the aimed compound having a hexagonal layer structure expressed by TmFeZn9O12. |
