Temperature dependence of linewidth in nano-contact based spin torque oscillators: effect of multiple oscillatory modes
P. K. Muduli, O. G. Heinonen, Johan Åkerman
We discuss the effect of mode transitions on the current (I) and temperature (T) dependent linewidth (Δf) in nanocontact based spin torque oscillators (STOs). At constant I, Δf exh…
Spin-torque oscillator linewidth narrowing under current modulation
Ye. Pogoryelov, P. K. Muduli, S. Bonetti +2
We study the behavior of the linewidth of a nano-contact based spin torque oscillator (STO) under application of a radio frequency (100 MHz) modulating current. We achieve a signif…
Bias dependence of perpendicular spin torque and of free and fixed layer eigenmodes in MgO-based nanopillars
P. K. Muduli, O. G. Heinonen, Johan Åkerman
We have measured the bias voltage and field dependence of eigenmode frequencies in a magnetic tunnel junction with MgO barrier. We show that both free layer (FL) and reference laye…
