Micromagnetic understanding of stochastic resonance driven by spin-transfertorque
G. Finocchio, I. N. Krivorotov, X. Cheng +2
In this paper, we employ micromagnetic simulations to study non-adiabatic stochastic resonance (NASR) excited by spin-transfer torque in a super-paramagnetic free layer nanomagnet…
Stochastic resonance of a nanomagnet excited by spin transfer torque
Xiao Cheng, Carl T. Boone, Jian Zhu +1
Spin transfer torque from spin-polarized electrical current can excite large-amplitude magnetization dynamics in metallic ferromagnets of nanoscale dimensions. Since magnetic aniso…
Rapid Domain Wall Motion in Permalloy Nanowires Excited by Spin-Polarized Current Applied Perpendicular to the Nanowire
C. T. Boone, J. A. Katine, M. Carey +3
We study domain wall (DW) dynamics in permalloy nanowires excited by alternating spin-polarized current applied perpendicular to the nanowire. Spin torque ferromagnetic resonance m…
Resonant Nonlinear Damping of Quantized Spin Waves in Ferromagnetic Nanowires
Carl Boone, Jordan Katine, Jeff Childress +5
We use spin torque ferromagnetic resonance to measure the spectral properties of dipole-exchange spin waves in permalloy nanowires. Our measurements reveal that geometric confineme…
Experimental Test of Analytic Theory of Spin Torque Oscillator Dynamics
C. Boone, J. A. Katine, J. R. Childress +3
We make measurements of power spectral density of the microwave voltage emitted by a spin torque nano-oscillator (STNO) and compare our experimental results to predictions of an an…
