Ferromagnets have been utilized in memory devices for decades, but attention has only recently shifted to antiferromagnets. Their compensated spins make their magnetism more challenging to harness and detect. However, the minimal stray fields of antiferromagnets hold promise for enabling the development of ultradense memory storage. With the Qnami ProteusQ, we can visualize their remaining uncompensated spins, which are found at domain walls, crystalline edges, or within nanostructures.
Applying inhomogeneous strain to chromium oxide thin films induces a strong vertical gradient of the Neel temperature inferred through scanning NV magnetometry measurements.
Scanning NV Magnetometry unveiled for the first time the nanoscale mechanics of antiferromagnetic domain walls opening new avenues for antiferromagnetic spintronics.
Scanning NV Magnetometry unlocks the characterization of the effects of strain and electrical fields on exotic antiferromagnetic spin textures in multiferroics.
