Domain wall theory and exchange stiffness in Co/Pd multilayers
نویسنده
چکیده
The stripe model of domain structure in multilayers is studied by micromagnetic simulation. The results indicate a strong reduction of the effective domain wall energy (by dipolar effects). Domain width measurements on sputtered C o /P d multilayers are compared with the theory. The estimated exchange stiffness is comparable with that of bulk Co. The effects of interface roughness and of interlayer exchange are discussed.

Magnetization reversal of Co/Pd multilayers on nanoporous templates
By making use of an e-beam deposition system, the [Co(2 Å)/Pd(10 Å)]15 multilayers were prepared on a Si(100) substrate and anodized aluminum oxide [AAO] templates with average pore diameters of around 185, 95, and 40 nm. The mechanism of magnetization reversal of the Co/Pd multilayers was investigated. Wall motion was observed on the Co/Pd multilayers grown on the Si substrate. A combination o...
متن کاملA novel method for quantitative study of domain reversal behavior
A novel method to quantitatively analyze the domain reversal behavior has been adopted to understand the total-thickness-dependent domain reversal behavior in Co/Pd multilayers. The wall-motion speed and the nucleation rate were simultaneously determined by analyzing serial domain images observed using a real-time domain observation system. Using this method, sensitive decrement of the wall-mot...
متن کاملMagnetization reversal in Co/Pd multilayers with varying Co sublayer thickness
We have investigated magnetization reversal in nanostructured Co/Pd multilayers. Interestingly enough, reversal phenomena in this system were found to be very sensitive to the Co-sublayer thickness and very contrasting reversal behaviors were observed between the samples having 2-Å-thick Co and 4-Å-thick Co sublayers. Direct domain observation and time-dependent magnetization viscosity curves r...
متن کاملField dependence of the activation volumes in Co/Pd multilayered films
The field dependence of the activation volumes of nucleation and wall-motion processes in magnetization reversal of Co/Pd multilayers is presented, as observed using a magneto-optical Kerr-effect microscope capable of real-time domain imaging in a wide time range of 10−5−103 s. The analytic forms of the activation volumes are derived from a theoretical consideration of equilibrium conditions of...
متن کاملObservation of unequal activation volumes of wall-motion and nucleation processes in Co/Pd multilayers.
We report the difference in activation volumes of wall-motion and nucleation processes in Co/Pd multilayers. Each activation volume was estimated from field dependence of wall-motion speed and nucleation rate, obtained by real-time domain imaging using a magneto-optical Kerr effect microscope. Delicate analysis shows that the two activation volumes are generally unequal and the ratio between th...
