摘要: Time-averaged images of the magnetization within single-layer spin-transfer oscillators have been obtained using holography with extended reference by autocorrelation linear differential operator technique. Transport measurements on a Pd(5)-Cu(20)-Ni81Fe19(7)-Cu(2)-Pd(2) (in nanometers) stack 100 nm diameter nanocontact reveal presence vortex dynamics. Magnetic device for injected current values 24 and −24 mA suggest that has ejected from become pinned at edge region is visible through Au mask.
