The control of domain walls or spin textures is crucial for spintronic applications of antiferromagnets. Despite many efforts, it has been challenging to directly visualize antiferromagnetic domains or domain walls with nanoscale resolution, especial

The compound MnSb${}_{2}$Te${}_{4}$ is a close relative of the intrinsic antiferromagnetic topological insulator MnBi${}_{2}$Te${}_{4}$. Density functional theory predicts that a Weyl semimetal phase exists in ferromagnetic MnBi${}_{2}$Te${}_{4}$. He

Here, we present microscopic evidence of the persistence of uniaxial A-type antiferromagnetic order to the surface layers of MnBi_{2}Te_{4} single crystals using magnetic force microscopy. Our results reveal termination-dependent magnetic contrast ac

The Hall effect in SrRuO$_3$ thin-films near the thickness limit for ferromagnetism shows an extra peak in addition to the ordinary and anomalous Hall effects. This extra peak has been attributed to a topological Hall effect due to two-dimensional sk

The current interest in materials supporting topological states calls for detailed electronic-structure characterization, via magnetometry in intense magnetic fields. A quartz tuning fork (QTF) could be an advantageous platform for this very challeng

Using femtosecond infrared nano-spectroscopy we probe spatial variations in vibrational coherence in molecular solids. With attomolar sensitivity we resolve the homogeneous response limit identifying static and dynamic heterogeneities in local chemic
