Abstract

Structural magnetic and spintronic properties of 1 Co2FeGe1 xSix and Co2FeGa1 xSix 2 Ru2FeSi1 xGex and Ru1 xCox 2FeSi and 3 Mn1 xCox 2VAl and Mn1 xCox 2VGa full Heusler alloys prepared by arc melting method followed by heat treatment Ab initio calculations have been performed on the Co and Ru alloys using generalized gradient approximation GGA and GGA U methods where U is the Hubbard potential Saturation magnetization Ms of For Co2FeGe1 xSix alloys with x gt 0 do not Slater Pau
