13 Jun 2006 | | Subject: | Materials Science | | Abstract: | We report the first confirmation of the rectifying effect in single-layer magnetic nanowires due to the radio frequency (RF) spin-polarized current. The rectifying effect in single layer magnetic nanowires has been observed when the RF current is applied under an applied magnetic field. The sign of the direct-current (DC) voltage has been reversed when the sign of the applied magnetic field is reversed. These experimental results suggested that RF current excited the intrinsic ferromagnetic resonance mode in the nanowires due to the spin transfer torque. The time-varying anisotropic magnetoresistance was generated by the intrinsic ferromagnetic resonance, and, as a result, it generated the DC voltage at the intrinsic ferromagnetic resonance frequency. | | Source: | arXiv, cond-mat/0606305 | | Services: | Forum | Review | PDF | Favorites | |
