Preferably a bit is encoded using a symmetric topological state of the domain wall and a topological state including at least one winding rotation of a magnetisation vector of the domain wall. Preferably the magnetic bubble is confined in an island of magnetic material, preferably of maximum dimension less than 1 μm.patentUS2016322114US2015380106US2015146469US2014177309US2013294131US2011261602WO2009141667GB080940339615987
