Antiferromagnetic Mn2Ge for Spintronics
In recent years researchers have started looking for antiferromagnetic materials for spintronic applications. There is distinct advantage of Antiferromagnetic materials over ferromagnetic. Antiferromagnetic remains robust against magnetic interference. They don't produce stray fields and display ultrafast dynamics. Binary metallic alloys are simple and prototype kind of materials systems to understand the spin dynamics. Here, in our computational laboratory, we design new binary alloys and we study their magnetic properties using density functional theory.

Fe2Ge in hexagonal symmetry becomes ferromagnetic. We have studied how the magnetic properties evolve in this material as a function of applied strain. We have discovered that Germanium, a non-magnetic element acts as a bridging atom between two magnetic Iron atoms and adds electronic charge to Iron atoms. This extra charge is going to increase the occupation of the majority spin band and ferromagnetic ordering increases according to Stoner model. This becomes very interesting to study the charge-induced magnetism in metallic alloys. Using Density functional theory calculations one can study the charge transfer from metal to ligand or ligand to metal charge transfer can bring new understanding and new tricks to design new ferromagnetic alloys.
