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 immediately shipped out. 
• Full characterization: Samples are characterized using variety of techniques all under inert gas conditions to confirm the crystalline quality.
