Anisotropic magnetic properties of novel correlated van der-Waals materials

Layered van der Waals crystals with Weak couplings between individual layers has generated enormous interest in scientific community, because of the presence of long range magnetic order down to monolayer limit. The family of transition metal trichalcogenides (TMTC) belongs to the class of layered van der Waals materials. These TMTCs exhibits many interesting physical properties such as the metal/insulator transition, magnetism, and superconductivity under pressure. Also, when thinned down to the monolayer limit, significant changes in the physical properties have been observed. Most of these properties steam from the strong 2D character associated with the layered crystal structure. Cr₂Ge₂Te₆ is a ferromagnetic insulator whereas Ni₂P₂S₆ & Fe₂P₂S₆ are aniferromagnetic insulators. In this talk, I will discuss about synthesis, physical properties and the tunability of their anisotropic magnetic properties of these novel TMTCs.
