CrI₃ (Chromium Triiodide)

CrI₃ is a layered van der Waals magnetic semiconductor from the chromium trihalide (CrX₃) family. The bulk is a ferromagnet (Curie temperature ≈ 61 K) with strong out-of-plane magnetic anisotropy, while thinned samples show layer-dependent magnetism—ferromagnetic in the monolayer and interlayer-antiferromagnetic in the bilayer—tunable by electric field, pressure, and stacking order. As one of the first confirmed two-dimensional ferromagnets, CrI₃ is a landmark material for research on 2D magnetism, magneto-optical effects, spintronics, and magnetic tunnel junctions.

Growth method: Chemical vapor transport (CVT).

Sample specifications: Individual crystals measure approximately 3–5 mm. CrI₃ is air-sensitive and is sealed under inert atmosphere. Each package contains multiple high-quality single-crystal pieces. Contact us for current stock details.

Exfoliation: Easy — readily cleaved into thin flakes by standard mechanical exfoliation.
