Since last decadeā€™s discovery of graphene, scientists have searched for its magnetic cousin: a magnetic material that can be cleaved down to a single monolayer thickness. One relatively little-studied family of suitable materials is the transition metal selenophosphates, a class of layered, van der Waals-bonded semiconductor materials. Caolan aims to synthesize single crystals of two members of this family, FePSe3 and NiPSe3, in order to perform magnetization measurements in an effort to understand the role of selenium in determining the direction of magnetic ordering. These materials are exciting candidates for both fundamental research in understanding low-dimensional magnetism and magnetoelectronic device applications such as high density ultrafast magnetic storage.
