摘要
Rectification of microwave oscillations of magnetization in a permalloy film is realized using the planar Hall effect. Two different rectified signals are obtained: a signal from the linearly excited uniform magnetization precession at the frequency of the external pumping and a signal from the pairs of contrapropagating short-wavelength spin waves parametrically generated at one-half of the pumping frequency. The second, most unusual, rectified signal is caused by the uniform component of the dynamic magnetization created due to the interference of the phase-correlated pairs of parametric spin waves.
