Abstract

We studied the response of a ferromagnet-insulator-normal metal tunnelnewlinestructure under an external oscillating radio frequency (R.F.) magnetic field.newlineThe D. C. voltage across the junction is calculated and is found not tonewlinedecrease despite the high resistance of the junction; instead, it is of thenewlineorder of $mu V$ to $100mu V$, much larger than the experimentally observednewlinevalue (100 nano-V) in the "strong coupled" ohmic ferromagnet-normal metalnewlinebilayers. This is consistent with recent experimental results in tunnelnewlinestructures, where the voltage is larger than $mu V$s. The damping and loss ofnewlinean external RF field in this structure is calculated.
