Studies of electronic, magnetic and optical properties of europium nitride EuN doped with TM (Ti, V, Cr and Co): Ab-initio calculation
چکیده انگلیسی
Specialized applications of spintronics devices have attracted much attention as an economical substitute for conventional magnetic recording technology. In this work, we performed ab-inito calculations for rare earth nitride EuN doped with 5% of (Ti, V, Cr and Co) using density functional theory (DFT). The calculations have been done through the Korringa-Kohn-Rostoker method (KKR) combined with the coherent potential approximation (CPA). The optical properties for Eu0.95TM0.05N were evaluated by calculating the optical absorption. From the calculation of density of states (DOS), it is found that some of the DMS Eu0.95TM0.05N doped with TM (Ti, V, Cr and Co) exhibit a half-metallic behavior with a high transition temperature, which makes them suitable for spintronic applications. Moreover, the optical absorption spectra also helped to identify the phase of the rare earth nitride Eu0.95TM0.05N.
