CoBi₂Te₄ (Cobalt Bismuth Telluride)

CoBi₂Te₄ is a member of the MnBi₂Te₄ family of intrinsic magnetic topological insulators, with cobalt in the magnetic layer. It is studied for the interplay of magnetism and topological band structure.

Growth method: Chemical vapor transport (CVT).

Sample specifications: Individual crystals measure approximately 3–4 mm, with a purity of up to 99.999% (5N), and 2–3 high-quality single-crystal pieces included in each package.

Exfoliation: Moderate — cleaves along the van der Waals planes into thin flakes.
