Abstract
The mechanical, electronic and magnetic properties of the full heusler alloys Ru 2 Ti 1-x Fe x Ge for the concentrations x = 0, 0.25, 0.5, 0.75, 1 using WIEN2k implementation of full potential linearized augmented plane wave (FP-LAPW) method in order to find a new compound for the spintronic applications within generalized gradient approximation (GGA) and modified Becke Johnson exchange potential with generalized gradient approximation (MBJ-GGA) as exchange correlation (XC) potential are reported for the first time. Our results show that the Fe incorporating in the Ru 2 TiGe created a half metallic (HM) gap at Fermi level (EF) in minority spin channel (MIC) and induced a magnetic moment on the paramagnetic Ru 2 TiGe . Moreover, the HM gap decreases with increasing the concentrations from 0.25 to 0.75, while the magnetic moment undergoes an inverse behavior.
