Description

Description Chromium triiodide is a rare layered transition metal trichalcogenide (TMTCs) ferromagnetic semiconductor. Unlike chromium trichloride, which exhibits 2D-Heisenberg magnetic behavior, CrI3 exhibits stronger magnetic anisotropy, promoting 3D magnetic properties, with a larger van der Waals gap and thus a smaller splitting energy.

Features And Benefits

Features And Benefits The magnetic properties of CrI3 depend on the layer thickness and stacking order. Bulk CrI3 is a ferromagnetic phase with a Curie temperature of 61 K in a rhombohedral stack, while few-layered CrI3 has a layered antiferromagnetic phase with a lower order temperature of 45 K in a monoclinic stack layer.

Application

Application 2D CrI3 is a promising candidate for van der Waals bonded ferromagnetic devices because its ferromagnetism can be preserved when the bulk crystal is exfoliated to its monolayer.
