Engineered magnetic domains with deliberately set magnetic properties and designed shapes in thin-film systems have proven to be useful in memory [1][2] and
experimentally found (d = 5 μm).
Conclusion
By employing the helium ion beam of a scanning helium ion microscope defocused to 8 nm for mask-less ionbombardmentinducedmagneticpatterning a prototypical in-plane exchange-biased layer system has been modified locally with a resulting patterned spot of less than
