“…Similar to the Kerr or Faraday effect in ferromagnets, birefringence imaging is based on the polarization rotation of reflected or transmitted light from an antiferromagnetic material. While differences in the birefringence of antiferromagnetic domains can originate directly from second order magneto-optical effects (Cotton-Mouton or Voigt Effect) 21,22 , birefringence of AFMs with a strong magnetoelastic coupling is often dominated by strain-induced birefringence [23][24][25] . Birefringence imaging using a polarizing microscope is a powerful and easily accessible tool to investigate the antiferromagnetic domain structure of bulk crystals 20,26 and thin films 27,28 .…”

Antiferromagnetic transition metal oxides are an established and widely studied materials system in the context of spin-based electronics, commonly used as passive elements in exchange bias-based memory devices. Currently, major interest has resurged due to the recent observation of long-distance spin transport, currentinduced switching, and THz emission. As a result, insulating transition metal oxides are now considered to be attractive candidates for active elements in novel spintronic devices. Here, we discuss some of the most promising materials systems and highlight recent advances in reading and writing antiferromagnetic ordering. This article aims to provide an overview of the current research and potential future directions in the field of antiferromagnetic insulatronics.
