Abstract
CrI${}_{3}$, a member of the two-dimensional family of materials, offers unique and very rich magnetic and electronic phases. The authors show experimental evidence for the transition from ferromagnetic semiconductor to antiferromagnetic metal at high pressure and low temperature. The junction between these phases is magnetically complex and reminiscent of quantum spin liquid or self-induced spin-glass state. Calculations using density functional theory suggest that competition between intralayer ferromagnetic and interlayer antiferromagnetic interactions is responsible for the emergence of the complex magnetic phase.
