Magnetoresistive Sensor Detectivity: A Comparative Analysis
J. E. Davies, J. D. Watts, J. Novotny +2
We report on the noise performance characteristics of magnetic sensors using both magnetic tunnel junction (MTJ) and giant magnetoresistance (GMR) elements. Each sensor studied has…
Imaging of Spin Dynamics in Closure Domain and Vortex Structures
J. P. Park, P. Eames, D. M. Engebretson +2
Time-resolved Kerr microscopy is used to study the excitations of individual micron- scale ferromagnetic thin film elements in their remnant state. Thin (18 nm) square elements wit…
Spatially Resolved Dynamics of Localized Spin-Wave Modes in Ferromagnetic Wires
J. P. Park, P. Eames, D. M. Engebretson +2
We have observed localized spin-wave modes in individual thin-film ferromagnetic wires using time-resolved Kerr microscopy as a micron-scale spectroscopic probe. The localization i…
