The only magnetic grade MnPSe3 vdW crystals in the commercial market. Our customers knows that slim amount of defects and magnetic impurities are sufficient to mask the observation of exotic magnetic behavior from 2D magnets. Our vdW magnets are created using state-of-the-art techniques to provide highest magnetic quality crystals through slow but high quality self-flux technique without using any contaminating transport agents.
MnPSe3 is a 2D Heisenberg-type magnetic material with Neel temperature at 77K  MnPSe3 crystals have been synthesized through chemical vapor transport (CVT) or flux transport technique (similar to CVT except chemical transport agent is not utilized to attain high crystallinity and purity) with confirmed 99.999% purity and high crystallinity. Each crystal measures few mm in size, and one order includes 3 pieces of MnPSe3 crystals. MnPSe3 flakes are perfectly oriented along 0001 (c-axis) direction. To date, MnPSe3 has been mostly studied in the bulk form. It has antiferromagnetic response but undergoes antiferromagnetic to ferromagnetic transition (AFM to FM) at low temperatures. More recently, MnPSe3 sheets have also been demonstrated to be an efficient photocatalytic and electrocatalytic material. All these products are handled using non-magnetic tweezers and in non-magnetic environment with tools that are free of magnetic impurities to ensure intrinsic magnetic properties can be confidently measured and probed.
