|Title:||Time and Frequency Domain Measurements of Ferromagnetic Resonance in Small Spin-Valve|
|Published:||September 01, 2000|
|Abstract:||Time and frequency domain magnetoresistance measurements of ferromagnetic resonance (FMR) in small spin-valvedevices are presented along with comparisons to single-domain simulations. The measurements and simulations give consistent results for rotational motion with angular deviations of less than 300 from the easy axis. While the time and frequency domain measurements produce similar results for ideal devices in the linear regime, each technique provides different information as the devices become nonlinear and less ideal. Both time and frequency domain magnetoresistance measurements allow the study of FMR in considerably smaller magnetic structures than can be done with conventional techniques.|
