Recent studies have experimentally discovered several host materials for antiskyrmions have been identified, but their control via thermal current remains elusive. An international team of researchers (Japan, Germany) used thermal current to drive the transformation between skyrmions, antiskyrmions and non-topological bubbles, as well as the switching of helical states in the antiskyrmion-hosting ferromagnet (Fe0.63Ni0.3Pd0.07)3P at room temperature. They discovered that a temperature gradient drove a transformation from antiskyrmions to non-topological bubbles to skyrmions while under a magnetic field and observed the opposite, unidirectional transformation from skyrmions to antiskyrmions at zero-field, suggesting that the antiskyrmion, more so than the skyrmion, was robustly metastable at zero field… read more.
