Cr₂Ge₂Te₆ (Chromium Germanium Telluride)

Cr₂Ge₂Te₆ is a layered van der Waals ferromagnetic semiconductor with out-of-plane magnetic anisotropy and a bulk Curie temperature of about 61 K. As one of the first intrinsic ferromagnetic semiconductors shown to retain magnetism down to the two-dimensional limit, its magnetism is tunable by electric field, pressure, and layer number. Combining magnetism with semiconducting behavior, Cr₂Ge₂Te₆ is a classic material for research on 2D magnetism, spintronics, and magnetic van der Waals heterostructures.

Growth method: Flux growth.

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.
