Abstract
On the basis of the concept of strong interaction in one unit cell, it is stated that ferromagnetic instability can occur in a system with hops between oxygen anions and transition metal (Me) cations in A1−x BxMeO3 compounds. A phase diagram is constructed to describe the occurrence of ferromagnetic ordering as a function of the average number of holes (h t, d) and (h p) in the low-spin or high-spin t 62g or high-spin 3d 10 shell of the transition metal and in the 2p 6 shells of O2−.
