Each pattern comprises many little magnetic poles winding around a core region in a clockwise or anti-clockwise manner, very much like air circulating inside a tornado or hurricane.<\/span><\/p><p>When realised experimentally, combinations of these anti-ferromagnetic whirls are predicted to be stable and dense structures which can potentially be moved along magnetic \u2018race tracks\u2019 at whirlwind speeds of a few kilometres per second! These could serve as mobile information components \u00a0to build energy-efficient and high-performance next-generation computing.<\/p><p>However, experimental progress in this field has been significantly inhibited by the difficulty of visualising and reproducibly controlling these anti-ferromagnetic materials, as they appear almost non-magnetic from afar.<\/p><p>To realise these textures, <span>Dr Hariom Jani<\/span> under Assoc Prof Ariando\u2019s guidance came up with a novel interdisciplinary strategy that combines high-quality film synthesis from materials engineering called pulsed laser deposition, magnetic phase transitions from physics, and topology from mathematics. Drawing inspiration from a historical idea which postulated the formation of cosmic whirls at special locations in the universe from a phase-transition of the early universe, they discovered a large family of antiferromagnetic whirls in an earth-abundant material, iron oxide, that are stable at room temperature and possess widely tuneable core sizes.<\/p><p>This work was published in\u00a0<i>Nature<\/i>\u00a0(February 2021).<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<\/div>\n\t\t","protected":false},"excerpt":{"rendered":"<p>Whirling vortex-like magnetic nano-textures in anti-ferromagnets are predicted to be highly robust, ultra-small and ultra-fast.
