This does not flip the vortex, but rather causes it to gyrate back and forth on the disk (see figure “When vortices collide”). By deliberately boosting the field to 1.5 mT for one period of ...

In magnetic bubbles, although these are "ancient" cylinder domains, the type-I bubbles (renamed as skyrmion bubbles with the same topology as skyrmions) have remotivated general scientific interests.
