Anomalous temperature dependence of the spontaneous magnetization of single-crystal La0.73Ba0.27MnO3

Detailed measurements of the spontaneous magnetization of single-crystal La0.73Ba0.27MnO3 are presented; these show a marked reduction in this property below 60 K which is consistent with a clearly discernible moment reduction, one of the few definitive conclusions about such effects provided by bulk measurements.
