Enhancement of spin-dependent scattering and improvement of microstructure in spin valves by delayed deposition
Appl. Phys. Lett. 86, 252503 (2005)，-0001，（）：
Si/Ta/Co/Cu/CoFeMn sor NiOd spin valves were prepared by a delayed sputtering procedure, in which depositions of Ta and followed layers were intervened by 1 h. The spin valves are found to have better coherent growth with stronger s111d preferred orientations in Co and Cu layers, compared with the traditional continuous method. At the same time, the giant magnetoresistance ratio and spin-dependent scattering are enhanced by a factor of 20%-30%. These results indicate that the coherent growth and the s111d preferred orientation can enhance the spin-dependent scattering of spin valves.
