Experimental study of intrinsic photocurrents in a 2D magnet
ORAL
Abstract
Crystal inversion breaking can lead to intrinsic photovoltaic responses without the need for pn junctions. These intrinsic responses can be tuned by controlling the crystal symmetry. While this effect in non-magnetic systems has been widely studied, an intriguing scenario arises when the lattice is inversion symmetric but the inversion symmetry is broken by spin structures in magnetic systems. In this case, the intrinsic photocurrent becomes strongly linked to the magnetic structure and can be controlled by magnetism. We will present our experimental findings on this effect in a 2D van der Waals magnet.
