Room temperature exchange bias in SmFeO3 single crystal

•Room temperature exchange bias has been discovered in single-crystalline SmFeO3.•Its pinning origin is attributed to the antiferromagnetic clusters.•Its being single phase and occurring at room temperature make it an appropriate candidate for application.

Exchange bias phenomenon is generally ascribed to the unidirectional magnetic shift along the field axes at interface of two magnetic materials. Room temperature exchange bias is found in SmFeO3 single crystal. The behavior after different cooling procedure is regular, and the training behavior is attributed to the athermal training and its pinning origin is attributed to the antiferromagnetic clusters. Its being single phase and occurring at room temperature make it an appropriate candidate for application.
