摘要

Abstract

BSTRACTTo broaden the scope of van der Waals 2D magnets

we report the synthesis and magnetism of covalent 2D magnetic Cr

with a thickness down to one-unit-cell. The 2D Cr

crystals exhibit robust ferromagnetism with a Curie temperature of 180 K

a large perpendicular anisotropy of 7 × 10

J m

−3

and a high coercivity of ∼4.6 kG at 20 K. First principles calculations further show a transition from canted to collinear ferromagnetism

a transition from perpendicular to in-plane anisotropy

and emergent half-metallic behavior in atomically-thin Cr

suggesting its potential application for injecting carriers with high spin polarization into spintronic devices.
