Magnetic properties of transition metal ion-doped AgCuS: an ab-initio calculation

ABSTRACT

Dilute magnetic semiconductor (DMS) is a trending research topic in material science for its requirements in spintronics technology in recent times. The present work reports the electrical and magnetic properties of different transition metal ions (Ti, V, Cr, Mn, Fe, Co, Ni and Zn)- doped silver copper sulphide. The dilute doping of transition metal ions at the copper site induces significant magnetic moments, which ordered ferromagnetically. The 3d orbital of the transition metal ions and the d orbital of Cu and Ag ions are the source of magnetisation.
