摘要：

We report the first measurement of temperature dependent microwave giant magnetoresistance and microwave anisotropic magnetoresistance derived from microwave surface impedance data from frequency-swept ferromagnetic resonance at X-band on Fe/Cr/Fe trilayer ultrathin films on GaAs by MBE. Angular variation of resonance frequencies show uniaxial anisotropy which is modulated by four-fold anisotropy for both the samples over the temperature range studied.
