Abstract

The electrical resistivity and GHz permittivity of (Co₃₅Fe ₅₂B₁₃)₇₆-(SiO_1.9)₂₄ hetero-amorphous granular films were investigated. Experimental evidences for the very large critical thickness of the films that made eddy current loss practically negligible in the GHz range were provided. The (CoFeB)-(SiO _1.9) films exhibited high resistivity of over 10,000 νωcm with a large uniaxial anisotropy field of 340-410 Oe.
