Abstract
The impact of cobalt and nitrogen on the structural, magnetic, and electronic properties of beryllium sulfur (BeS) is investigated in this work using the Korringa Kohn Rostoker (KKR) approach in conjunction with the coherent potential approximation (CPA) and the generalized gradient approximation (GGA). The density of states for Co and N doping indicates a half metallic (HM) behavior with a spin polarization reaching up to 100% at Fermi level. In addition, when increasing the concentration of dopants, the Curie temperature of BeS rises to maximum values of 494.66K and 691.80K for Co and N doped BeS respectively. The stability of the ferromagnetic order (FM) in these compounds is attributed to double-exchange interaction processes. According to our results, these new diluted materials show great potential for spintronic devices.
