This paper describes the ex- perimental results of high resistivity granular films with soft magnetic properties. After estimation of the resistivity needed to suppress eddy current loss at over tens of MHz, we investigate material parameters governing formation process and thermal stability of the granular structure that realizes this resistivity. Furthermore, we propose a model of the extraordinarily high uniaxial anisotropy which has been frequently observed for the granular films and present some experimental evidences.
