Magnetic properties and high frequency characteristics of obliquely sputtered Co 100-xM x (M = V and Nb) films were investigated. All studied films exhibited strong induced in-plane uniaxial magnetic anisotropy. Less content of Nb (x = 7) than V (x = 16) is sufficient for Co 100-xM x films to become fully amorphous which exhibit the maximum magnetic anisotropy filed, reduced coercivity and the increased resistivity. The optimal properties of 4πM s = 11.3 kG, H k = 350 Oe and f FMR = 5.6 GHz are attained for Co 93Nb 7 film, which are suitable for up to 5 GHz applications. ? 2012 Elsevier B.V.
