A new method of the modifying factor for determining the broadband complex permeability of magnetic thin films, was proposed. Based on the measurement technology of shot-end microstrip line and the new modify factor, a series of FeCo-based magnetic thin films deposited on the oxidized silicon substrates and with an in-plane uniaxial anisotropy were measured in the frequency range of 0.5-5 GHz. The results fit well with the Landau-Lifchitz-Gilbert theory in a broad frequency range.
