Bismuth Ferrite (BFO) is an intriguing material. At room temperature, it exhibits a canted antiferromagnetic order and ferroelectricity. In this material, the spin arrangement and the electric polarization are coupled. This allows to change the magnetic order in the system by purely electrical means, thus promising ultra-efficient next-generation spintronic devices.
Peter Meisenheimer (UC Berkeley) and colleagues recently demonstrated the electrical switching of magnetic textures in BFO. The spins in BFO are arranged as spin-cycloids, that is, they form large superstructures. Using Scanning NV Microscopy, the team was able to…
