N2 - Co-Fe-Al-O nanogranular thin films for magnetoelastic device applications in the GHz frequency range are fabricated by RF-magnetron sputtering under an Ar+O2 atmosphere. A very large resistivity up to 400μΩcm, a saturation magnetization (4πMS) of 16kG and an anisotropy field of 45Oe are consistently obtained, resulting in excellent high-frequency magnetic properties, such as a high ferromagnetic resonance frequency of 2.3GHz combined with a large real part of permeability of 315. A saturation magnetostriction of 45ppm is achieved at a magnetic field as low as 20Oe.
