|Title:||Spectroscopic defect imaging in magnetic nanostructure arrays|
|Published:||July 25, 2012|
|Abstract:||We report a demonstration of spectroscopic defect imaging in an array of ferromagnetic structures using ferromagnetic resonance force microscopy (FMRFM). The arrray of 200 nm diameter circular dots includes a single oval-shaped ,defect.Š The technique resolves not only intentional differences in resonant field between the dots and the oval, but also differences between nominally identical circular dots in the array.|
