Abstract:

A wide range of investigation is going on to study kagome lattice to create a device with perfect conductivity. Here, we perform density functional calculation using FPLO code to study the electronic and magnetic properties of MgFe6Ge4, a kagome system, where we noticed the material to be ferromagnetic with a total magnetic moment of 11.38 µB/unit cell. We found the metallic nature where Fe-3d shows the highest contribution at the Fermi level in total DOS. Hybridization between Fe-3d and Ge-4p is observed around the Fermi level. The Wannier fitting with the DFT calculations was performed to obtain Wannier Hamiltonian to explore the Weyl points in MgFe6Ge4.
