|Title:||Current-driven switching in a single exchange-biased ferromagnetic layer|
|Published:||July 09, 2004|
|Abstract:||We demonstrate spin-transfer torque effects in a single exchange-biased ferromagnetic layer. A current through a point contact to the exchange-biased Co layer reverses the magnetization of a nanodomain in the layer hysteretically for low applied magnetic fields and reversibly for high fields (up to 9 T). These effects are the inverse of the domain wall magnetoresistance, in the same way that similar effects in multilayers are the inverse of giant magnetoresistance.|
