- 論文の詳細を見る
The theory of the random magnetic mixture of several kinds of magnetic atoms developed in I is applied to the classical Heisenberg system (S=∞) at T=0. The ferromagnetic, ferrimagnetic and antiferromagnetic phases are obtained in the binary mixture of two kinds of magnetic atoms corresponding to the types and concentrations of those atoms. The possibility of finding an unstable phase with the infinite susceptibility without the spontaneous magnetization is also discussed. The magnetization process and the qualitative feature of the phase transition are studied in detail.
