Direct Visualization of Magnetic Domains and Moire Magnetism in Twisted 2D Magnets - II

ORAL

Abstract

Twist engineering of two-dimensional (2D) materials has proven to be a highly effective method of achieving exotic correlated and topological states.  Employing this approach to the 2D magnet chromium triiodide (CrI3) has allowed for quantitative spatial imaging of twist-engineered nanoscale magnetic domains and patterns, detected via Nitrogen Vacancy (NV) magnetometry. Here, we discuss the magnetic behavior of twisted double bilayer CrI­3. Using scanning NV magnetometry in conjunction with magneto-optical techniques, we characterize the emergent magnetic domain structure in these samples. Our results highlight the potential of twisted 2D magnets in engineering noncollinear magnetic states.
