BiFeO 3 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 BiFeO 3 layers in close proximity to La 0.7 Sr 0.3 MnO 3 . Simultaneously, ultrathin BiFeO 3 exhibits excellent piezoresponse. These findings provide a promising avenue towards achieving the multiferroic devices. (Image credit: Jill D. Hemman, SNS at ORNL).
