Bismuth ferrite is considered one of the most promising materials for low-power antiferromagnetic spintronics. It is a room-temperature multiferroic material where antiferromagnetic spin textures can be controlled by electric fields. Despite the interest in bismuth ferrite increased over the past two decades, a quantitative characterization of the ferroelectric domains and their spin textures is still missing.
In their recently published paper, the team led by Dr. Vincent Garcia (Unité Mixte de Physique, CNRS, Thales) shows how Scanning NV Magnetometry allows to map different types of spin cycloids stabilized in strain-engineered bismuth ferrite thin films and extract their relevant physical parameters….
