In this work we present a systematic study of the crystallographic structure and the magnetic ordering of LaMnO 3Ψ perovskites. Changing the oxygen composition within the range 2.995 < 3 Ψ < 3.140, we found a 3 Ψ 1 value (3.04 < 3 Ψ 1 < 3.05) which de5nes a boundary in the magnetic phase diagram T v
Magnetism of matters has two basic ingredients. While exchange and correlation are responsible to the stability of magnetic moment, magnetic ordering is controlled by orbital hybridization, which depends on the atomic arrangement and the mode of orbital occupation. Transition-metal oxides serve as a
