It is established, that the coercivity observed in physically - nonpercolated nanogranular (CoFeB)0.6-(SiO2)0.4 films with oriented anisotropy of the granules has an anomalous angular dependence with the maximum near the hard in-plane magnetization direction and related to existence of superferromagnetic state in the samples. An investigation of the granular Co-Al2O3 systems allow us to establish a grown-induced anisotropy of granules. Peculiarities of the ferromagnetic resonance and magnetization reversal kinetics under influence of demagnetization field have been studied both experimentally and theoretically in these samples.
