Microwave power generated by a spin-torque oscillator in the presence of noise
Vasil Tiberkevich, Joo-Von Kim, Andrei Slavin
An expression for the microwave power generated by a spin-torque oscillator in the presence of thermal noise is derived. This expression, when used in a subcritical regime, demonst…
Excitation of self-localized spin-wave "bullets" by spin-polarized current in in-plane magnetized magnetic nano-contacts: a micromagnetic study
G. Consolo, B. Azzerboni, G. Gerhart +3
It was shown by micromagnetic simulation that a current-driven in-plane magnetized magnetic nano-contact, besides a quasi-linear propagating ("Slonczewski") spin wave mode, can als…
Generation linewidth of an auto-oscillator with a nonlinear frequency shift: Spin-torque nano-oscillator
Joo-Von Kim, Vasil Tiberkevich, Andrei N. Slavin
It is shown that the generation linewidth of an auto-oscillator with a nonlinear frequency shift (i.e. an auto-oscillator in which frequency depends on the oscillation amplitude) i…
Spectroscopy of the parametric magnons excited by 4-wave process
G. De Loubens, V. V. Naletov, Vincent Charbois +3
Using a Magnetic Resonace Force Microscope, we have performed ferromagnetic resonance (FMR) spectroscopy on parametric magnons created by 4-wave process. This is achieved by measur…
