  We report the magnetic imaging of ferromagnetic domains in the van der Waals
single crystal MnSb2Te4 from two different sources using cryogenic magnetic
force microscopy. The magnetic field dependence of the domains reveals very
weak pinning of domain walls in MnSb2Te4, resulting in a negligibly small
magnetic hysteresis loop. The temperature dependence of the domain contrast
reveals a mean field like behavior, in good agreement with that of bulk
magnetization measurements.
