We have identified an important microstructural origin of the switching field distribution (SFD) in patterned Co/Pd multilayer nanodots. In this study, we patterned a marked array of 115 nm Co/Pd multilayered nanodots on 50-nm thick silicon nitride

Common Reversal Mechanisms and Correlation Between Transient Domain States and Field Sweep Rate in Patterned Permalloy Structures

August 20, 2007

June W. Lau, M Beleggia, Y Zhu

Complicated domain configurations generated during the magnetization reversal of Permalloy elements patterned in various shapes are the results of a surprisingly few switching mechanisms. By comparing the results from micromagnetic simulations with the

Correlation of Edge Roughness to Nucleation Field and Nucleation Field Distribution in Patterned Permalloy Elements

July 31, 2007

A direct consequence of shrinking technology down into the nanoscale is the steadily increasing boundary to volume ratio. In the case of magnetic nanostructures, this trend emphasizes the role of edges on switching behavior. Magnetic nanostructures have
