Time Domain Mapping of Spin Torque Oscillator Effective Energy
Graham E. Rowlands, Jordan A. Katine, Juergen Langer +2
Stochastic dynamics of spin torque oscillators (STOs) can be described in terms of magnetization drift and diffusion over a current-dependent effective energy surface given by the…
Voltage-Induced Ferromagnetic Resonance in Magnetic Tunnel Junctions
Jian Zhu, J. A. Katine, Graham E. Rowlands +8
We demonstrate excitation of ferromagnetic resonance in CoFeB/MgO/CoFeB magnetic tunnel junctions (MTJs) by the combined action of voltage-controlled magnetic anisotropy (VCMA) and…
Angular Dependence of the Superconducting Transition Temperature in Ferromagnet-Superconductor-Ferromagnet Trilayers
Jian Zhu, Ilya N. Krivorotov, Klaus Halterman +1
The superconducting transition temperature, , of a ferromagnet (F) - superconductor (S) - ferromagnet trilayer depends on the mutual orientation of the magnetic moments of the…
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…
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…
