CrBr₃ (Chromium Bromide)

CrBr₃ is a layered van der Waals magnetic semiconductor from the chromium trihalide (CrX₃) family. It orders ferromagnetically both within and between layers (a bulk ferromagnet with a Curie temperature of about 37 K), exhibits out-of-plane magnetic anisotropy, and retains its ferromagnetism—externally tunable—down to the few-layer limit. Combining magnetism with semiconducting behavior, CrBr₃ is a classic material for research on two-dimensional magnetism, magneto-optical effects, and spintronic devices.

Growth method: Chemical vapor transport (CVT).

Sample specifications: Individual crystals measure approximately 3 mm, with a purity of up to 99.9999% (6N), and multiple high-quality single-crystal pieces included in each package.

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