The authors report on current-induced magnetization switching (CIMS) in current-perpendicular-to-plane exchange-biased spin-valve nanopillars with a low aspect ratio of 1. Due to the complex domain structure of the nanopillars, an intermediate resistance state has been clearly observed in the CIMS curve. A distinctive current-driven resistance oscillation and a very low critical current density of 6 × 105 A/cm2 have been demonstrated and explained to result from the competition between magnetic field, spin torque, and thermal activation.
