Defect induced, layer-modulated magnetism in ultrathin metallic PtSe₂.

ABSTRACT: Defects are ubiquitous in solids and often introduce new properties that are absent in pristine materials. One of the opportunities offered by these crystal imperfections is an extrinsically induced long-range magnetic ordering¹, a long-time subject of theoretical investigations^1-3. Intrinsic, two-dimensional (2D) magnetic materials^4-7 are attracting increasing attention for their unique properties, which include layer-dependent magnetism⁴ and electric field modulation⁶. Yet, to induce magnetism into otherwise non-magnetic 2D materials remains a challenge. Here we investigate magneto-transport properties of ultrathin PtSe₂ crystals and demonstrate an unexpected magnetism. Our electrical measurements show the existence of eit
