Conventional ferromagnetic resonance for magnetic thin films is found to coexist with the transmission resonance of a T-type microwave microstrip at certain applied magnetic fields. The conductivity, the magnetization and the magnetic anisotropic field of magnetic films can eventually be evolved from the measured resonance frequency and the quality (Q) factor of the resonance spectra. This work provides a closely scrutinized method to delineate the magnetic and electrical properties of the deposited magnetic films succinctly.
