CrI₃ Crystals

Description

CrI₃ Crystals (Chromium Triiodide)

CrI₃ is a layered magnetic material with a van der Waals structure, known for its intrinsic ferromagnetism in the monolayer and antiferromagnetic coupling in few-layer forms. It exhibits strong spin-orbit coupling, magnetic anisotropy, and excellent exfoliation properties, making it a key material for studying 2D magnetism, spintronics, and quantum materials. Our CrI₃ crystals are synthesized using the Chemical Vapor Transport (CVT) method, ensuring high purity, precise stoichiometry, and superior crystallinity.
