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?xBxMeO3 compounds. A phase diagram is constructed to describe the occurrence of ferromagnetic ordering as a function of the average number of holes (ht, d) and (hp) in the low-spin or high-spin t 2g 6 or high-spin 3d10 shell of the transition metal and in the 2p6 shells of O2?. |
