CrI3 (chromium triiodide) is a ferromagnetic semiconductor with Curie temperature (Tc) 61 K with significant magnetic anisotropy. Unlike other ferromagnetic vdW crystals the ferromagnetic order is also present down to monolayers (Tc of 45 K), and the magnetic behavior of CrI3 can be well described by the Ising model. Our CrI3 crystals are grown using chemical vapor transport technique at our facilities. Based on our experience, the amount of vacancy defects plan a vital role is their stability as well as FM response.

Perfect crystallization: In our growth process, we pay close attention to creating perfect crystals, each and every crystal is handled and characterized under vacuum or Argon environment.
Sample packaging: Samples are purged with Ar gas multiple times, pumped down to 1E-6 Torr pressures to ensure crystals do not interact with the residual gases.
Fresh samples: Crystals are always freshly grown and immediay shipped out.
Full characterization: Samples are characterized using variety of techniques all under inert gas conditions to confirm the crystalline quality.
