The magnetic states of a van der Waals ferromagnet CrGeTe3 probed by vector-field magnetic force microscopy

Abstract

We present a study on the magnetic domain configuration in the van der Waals ferromagnet CrGeTe3 using a vectorfield cryogenic magnetic force microscopy. Our investigation demonstrates the influence of magnetic fields strength and angle on the magnetic domain configuration, showing the coexistence of striped and spike-like magnetic domains. This study contributes to understanding the impact of uniaxial magnetic anisotropy on the domain configuration of van der Waals ferromagnets, offering insights into stabilizing different domain patterns.
