Abstract
We obtain the magnetic phase diagram of perovskite Mn oxides at low tempera tures. Our results show that when temperature T --> 0 a spiral state is sta ble in a lower doping concentration, a canted state is stable in a higher d oping concentration and a ferromagnetic (FM) state becomes stable in the in termediate doping concentration. With temperature increasing, a paramagneti c (PM) state appears at the higher doping concentration and then the canted state disappears.
