Nanogranular magnetic FeCo-A1N films were fabricated by plasma jet technique. Magnetic anisotropy in the films was induced by applied external magnetic field during the deposition. X-ray diffraction and chemical analysis revealed that the films consist of crystalline FeCo grains with the size of about 10 nm and amorphous A1N matrix. Hysteresis loops were measured using an AC hysteresis loop tracer at 101 Hz. The frequency dependence of permeability was investigated in the range of 0.1-2 GHz by a strip line permeameter. The highest characteristic frequency at which the natural ferromagnetic resonance occurs is about 1.7 GHz.
