Magnetization reversal in Co/Pd multilayers with varying Co sublayer thickness
نویسندگان
چکیده
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 revealed the wall-motion dominant reversal in the former samples, and the nucleation dominant reversal in the latter samples. Magnetization reversal in Co/Pd multilayers was theoretically studied by Monte Carlo simulation and experimentally observed reversal behaviors could be well explained. © 1997 American Institute of Physics. @S0021-8979~97!33408-2#

Spin dynamics in Co/Pd multilayers by varying the number of repeats
The spin reversal of nanostructured Co/Pd multilayers by varying the number of repeats has been investigated quantitatively. The magnetization viscosity measurement and the direct observation of the time-dependent spin reversal patterns showed that their reversal behavior gradually changed from wall-motion dominant to nucleation dominant by increasing the number of repeats. Both the wall-motion...
متن کاملMagnetization 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...

Ni-Co/Cu multilayers have been grown by electrodeposition method from a single electrolyte (based on Ni(SO4).6H2O, Co(SO4).7H2O, Cu(SO4) and H3BO3) using galvanostatic control on titanium sublayers. The X-ray diffraction (XRD) patterns confirmed the multilayered structure with the nanometer thicknesses. Also, electron diffraction x-ray (EDX) analysis confirmed the purity of deposited samples. ...
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 کاملAsymmetric domain nucleation and unusual magnetization reversal in ultrathin Co films with perpendicular anisotropy.
We report unexpected phenomena during magnetization reversal in ultrathin Co films and Co/Pt multilayers with perpendicular anisotropy. Using magneto-optical Kerr microscopy and magnetic force microscopy we have observed asymmetrical nucleation centers where the reversal begins for one direction of the field only and is characterized by an acute asymmetry of domain-wall mobility. We have also o...
