A combination of RF electrical characterization and time-resolved scanning Kerr microscopy has been used to image the magnetization dynamics excited in the continuous film NiFe free layer of a pair of nanocontact spin torque vortex oscillators (NC-STVOs). The NC-STVO is composed of Pd/Cu/Co/Cu/NiFe/Cu/Pd spin valve stack fabricated on a SiO substrate. 2-terminal magnetoresistance measurements are carried out in parallel electrical configuration for RF electrical characterization.
