Influence of phase separation on the low-field magnetic properties of La1−xSrxMn1−yFeyO3

The magnetic properties of ceramic La1−xSrxMn1−yFeyO3 samples with x = 0.3 and y = 0.15−0.25 are investigated in magnetic fields of B = 10−103 G at a temperature T between 5−310 K. A ferromagnetic transition at TC, decreasing considerably with y, is accompanied with strong magnetic irreversibility a...
