Vortex domain interaction and surface pinning effects of 10 nm to 80 nm magnetic nanoislands

Summary form only given. The authors study the vortex domain nanoislands, with the length-to-width ratio (LTW) and inter-island edge distance (IED) as parameters. Co rectangular dots with "fan-type" vortex domain were studied by magnetic force microscopy (MFM). Multivortices appear as the...

Description
Summary:Summary form only given. The authors study the vortex domain nanoislands, with the length-to-width ratio (LTW) and inter-island edge distance (IED) as parameters. Co rectangular dots with "fan-type" vortex domain were studied by magnetic force microscopy (MFM). Multivortices appear as the LTW increases and vortices coalesce. As the IED decreases, magnetostatic interactions become stronger and vortex domains change to combined Bloch and Neel domain walls. Some vortices disappear.
