BiFeO3 in the bulk is antiferromagnetically ordered—it lacks a magnetic handle that can be readily changed with magnetic fields. In article number 1700790, Er-Jia Guo, Michael R. Fitzsimmons and co-workers report a high-temperature large interfacial net magnetization in thin BiFeO3 layers in close proximity to La0.7Sr0.3MnO3. Simultaneously, ultrathin BiFeO3 exhibits excellent piezoresponse. These findings provide a promising avenue towards achieving the multiferroic devices. (Image credit: Jill D. Hemman, SNS at ORNL).
