A microwave interferometer of the Michelson-type to improve the dynamic range of broadband ferromagnetic resonance measurements
Eric R. J. Edwards, Anthony B. Kos, Mathias Weiler +1
We present a Michelson-type microwave interferometer for use in ferromagnetic resonance experiments. The interferometer is capable of broadband operation without manual adjustment…
Thermal Relaxation Rates of Magnetic Nanoparticles in the Presence of Magnetic Fields and Spin-Transfer Effects
William Rippard, Ranko Heindl, Matthew Pufall +2
We have measured the relaxation time of a thermally unstable ferromagnetic nanoparticle incorporated into a magnetic tunnel junction (MTJ) as a function of applied magnetic field,…
Time domain measurement of phase noise in a spin torque oscillator
Mark W. Keller, A. B. Kos, T. J. Silva +2
We measure oscillator phase from the zero crossings of the voltage vs. time waveform of a spin torque nanocontact oscillating in a vortex mode. The power spectrum of the phase nois…
Large angle magnetization dynamics measured by time-resolved ferromagnetic resonance
Th. Gerrits, M. L. Schneider, A. B. Kos +1
A time-resolved ferromagnetic resonance technique was used to investigate the magnetization dynamics of a 10 nm thin Permalloy film. The experiment consisted of a sequence of magne…
