    Current-induced magnetization dynamics in asymmetric CuCoCu single magnetic layer nanopillars has been studied experimentally at room temperature and in low magnetic fields applied perpendicular to the thin film plane. In sub-100 nm junctions produced using a nanostencil process a bistable state with two distinct resistance values is observed. Current sweeps at fixed applied fields reveal hysteretic and abrupt transitions between these two resistance states. The current induced resistance change is 0.5%, five times greater than the anisotropic magnetoresistance effect. We present an experimentally obtained low field phase diagram of current-induced magnetization dynamics in single ferromagnetic layer pillar junctions.
