Defects can significantly affect\nperformance of nanopatterned magnetic devices, therefore their influence on the\nmaterial properties has to be understood well before the material is used in\ntechnological applications.

The findings described in their article show that magnetic properties and domain configuration in\nnanopatterned systems are strongly determined by the defects, the heterogeneity\nof the nanostructure sizes and edge corrugations, and that such imperfections\nplay a key role in the processes of magnetic reversal.*<\/p>\n\n\n\n

The magnetic imaging described in the article cited above was performed using NanoWorld MFMR AFM probes <\/a>for magnetic force microscopy (MFMR).<\/p>\n\n\n\n
