Wave Polarization and Left-handed Materials in Metallic Magnetic Thin Films

摘要：

We have theoretically investigated the high-frequency response of magnetized metallic magnetic thin films. We found that magnetic films may become left-handed materials (LHM) in the vicinity of the ferromagnetic resonance frequency for incident waves with right-hand circular polarization (RCP) and linear polarization (LP). The frequency range where LHM exists depends on the waves polarization, and the magnetic damping coefficient, the ferromagnetic characteristic frequency of the film. There also exists a critical damping coefficient αc, above which the left-handed properties disappear completely.
