"Internal effective field sources for spin torque nanopillar oscillators";
Journal of Applied Physics, 105 (2009), S. 053901-1 - 053901-6.



Kurzfassung englisch:
In this paper we numerically conduct micromagnetic modeling with an expended micromagnetic model that includes the spin torque term and an impedance model to investigate methods to replace external field sources with internal ones and to investigate its tuneability on nanopillar geometries. We present results for three methods: interlayer coupling, large perpendicular anisotropy, and magnetostatic coupling. The internal field sources are evaluated as function of frequency shift with current, its dependency on temperature, and are tested against analytical predictions.
