Ferromagnetism of binary compounds with cubic symmetry

Based on the idea of a strong interaction within the same unit cell, the po ssible existence of a ferromagnetic instability in a system with jumps from transition element cations to nontransition element anions and vice versa is established. A phase diagram is constructed for the ferromagnetic orderi ng as a function of the degree of filling, n(p) and n(d), of the p(6)- and d(10)-shells of non-transition and transition elements, respectively.
