摘要

The electronic and magnetic properties of Cu-doped Full-Heusler Co2ZrSn compound are investigated using first-principles calculations. The Cu-doping at Co-site (Cu@Co) exhibits a substantial impact on the physical properties of Co2ZrSn system. Half-metallic ferromagnetism is evident within the GGA method for the undoped system, while the GGA+U scheme diminishes the half-metallicity. Our calculations show that as Cu-concentration increases, the total magnetic moment of the system decrease and become non-magnetic for 75% and 100% Cu-doping within GGA and GGA+U methods, respectively. Furthermore, spin-polarization is computed, which is an important parameter for the utilization of magnetic materials in spintronic devices. Finally, the doped structure's stability is analyzed by calculating the formation energies.
