Characteristics of a monolithically integrated microstrip with a thin-film Ni₈₀Fe₂₀ ferromagnetic core are studied. Ni₈₀Fe₂₀ film was electroplated on Si substrate in an external dc magnetic field (80 m T) along the strip line direction. The structure exhibits a peak attenuation of-19dB/cm at 2.8 GHz, a large wavelength reduction 60% at 1GHz, and over 100% enhancement of quality factor compared to the control devices.
