| Abstract |
The effects of composition and heal. treatment on the magnetic properties of Nd-Fe-Oxides were investigated. High coercivity of 5.5 kOe was obtained from the oxide which had atomic ratio of Fe₂ O₃/Nd₂=4/1. The optimum heat treatment condition of this sample was 1300℃ For 3 hours. The X-ray and SEM experiments revealed that the sample was composed of NdFeO₃ and α-Fe₂O₃. It seems that the high coercivity was due to NdFeO₃ phase. |
