Abstract: | Spin glass—ferromagnetic systems such as AuFe alloys having both the ferromagnetic and RKKY interactions are studied on the basis of a mean-random-field approximation. We obtain the phase diagram of the systems in terms of the temperature and the magnetic impurity concentration. The results roughly explain the magnetism of AuFe type alloys. |
