In our first application note, we show how Qnami ProteusQ™ can be used to image antiferromagnetic spin textures with state-of-the-art accuracy. We present two modes of operation allowing to rapidly converge towards quantitative understanding of the magnetic textures at the surface of an antiferromagnet. We use BiFeO3 as a prototype example, where we reveal spin cycloidal antiferromagnetic order with a performance that compares favorably with the recent literature.
BiFeO3 is a room-temperature multiferroïc presenting key properties for future spin-based electronics.
