Spectroscopic defect imaging in magnetic nanostructure arrays
Han-Jong H. Chia, Feng Guo, Lyubov Belova, Robert McMichael
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." 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.
