Magnetic properties of thin films

Antiferromagnetic resonance (AFMR) experiments on a well characterized single-crystal sample of have been performed using a spectrometer with wide ranges of both frequency and magnetic field. All the AFMR modes predicted from the theory have been observed. We find a significant contribution of the non-linear term in the expression of the AFMR frequency to the temperature dependence of the resonance point in the high-field low-frequency region.
