Scientists have discovered magnetic bubbles in iron-platinum nanodots that could be used to provide data storage solutions.

Nanotechweb reports that researchers from Cambridge University have observed the mathematical objects and have also seen triple-domain states consisting of concentric rings with alternating magnetisation in the iron-platinum nanodots.

"Magnetic nanodots are 'labs' for studying a hierarchy of mathematical objects," Christoforos Moutafis, of Cambridge University, explained to Nanotechweb.

He added that the iron-platinum alloy displayed "some extraordinary magnetic properties", explaining that this makes it a good candidate for future technological applications such as data storage.

The ultra-fast switching made capable by the iron-platinum nanodots is "very important" because this offers short operation times, which Mr Moutafis explained is a "prerequisite in modern devices".
