Electrodeposition of Periodically Nanostructured Straight Cobalt Filament Arrays

摘要: Arrays of straight cobalt filaments with periodic corrugation on the surface are electrodeposited a glass substrate without using templates. The corrugated structures induced by spontaneous oscillation electric voltage in electrodeposition, and periodicity can be tuned applying different currents. Magnetic force microscopy indicates that when interfilament separation is large, magnetic domains regularly aligned filament. Each structure filament corresponds to local single domain. become random becomes very small. We suggest our results could helpful understanding formation domain patterns microscopic scale may have potential application spintronics.
