Nanofabrication of spin-transfer torque devices by a PMMA mask one step process: GMR versus single layer devices
arXiv:cond-mat/0610277 · doi:10.1063/1.2717544
Abstract
We present a method to prepare magnetic spin torque devices of low specific resistance in a one step lithography process. The quality of the pillar devices is demonstrated for a standard magnetic double layer device. For single layer devices, we found hysteretic switching and a more complex dynamical excitation pattern in higher fields. A simple model to explain the resistance spikes is presented.
