Moiré-induced metamagnetic phases in hexagonal-twisted double bilayers of chromium triiodide

ORAL

Abstract

Magnetic moiré superlattices serve as a new and promising platform for realizing novel magnetic phases. Here, we report the observation of moiré-induced metamagnetic phases in hexagonal-twisted double bilayers of CrI3 (htDB-CrI3). We first show that htDB-CrI3 systems have a clearly higher moiré crystalline quality than the rhombohedral-twisted counterpart. Further, we will show the zero magnetization at zero field in the twisted regime, using both magnetic circular dichroism and scanning NV microscopy. But once the magnetic field is applied, a metamagnetic behavior develops that shows a hysteresis loop centering at a finite magnetic field. We will discuss our results with the insight from theoretical modeling.
