We fabricated a three-terminal MgO-based magnetic tunnel junction including a free layer for use as a vortex-type spin structure. The resonant motion of the magnetic vortex core, excited by the application of rf current to the free layer, was successfully detected through the tunneling magnetoresistance effect using a homodyne detection technique. By analyzing the detected dc signal, we were able to qualitatively estimate the efficiency of the spin-transfer induced excitation. From the parameters obtained in the experiment, we found that substantial voltage gain can be realized with this device.
