Bismuth ferrite has been in the spotlight for a while as an optimal candidate for energy-efficient devices. The coexistence of ferroelectric and antiferromagnetic orders at room temperature opens the avenue for electrically controlled antiferromagnetic spintronics.
What hinders the integration of multiferroics such as bismuth ferrite (BFO) in applications-relevant devices is the multi-directional spin cycloid domains which pose a challenge to deterministic magnetoelectric coupling. A collaboration led by Dr. Vincent Garcia (Unité Mixte de Physique CNRS/Thales) showed how …
