Room-temperature ferromagnetism in 2D van der Waals (vdW) materials, such as Fe3GaTe2 (FGaT), has garnered significant interest as a robust platform for 2D spintronic applications. Although many fundamental operations essential for the realization of 2D spintronics devices are experimentally confirmed using these materials at room temperature, the potential applications of magnetic skyrmions in FGaT systems at room temperature remain unexplored. An international team of researchers (Republic of Korea, USA – Lawrence Berkeley National Laboratory) showed the current-induced generation of magnetic skyrmions in FGaT flakes employing high-resolution magnetic transmission soft X-ray microscopy using a mechanism based on thermal effects. Direct observation of the skyrmion motion was demonstrated with ultra-low threshold current density. According to the researchers their work highlights the potential of FGaT as a foundation for room-temperature-operating 2D skyrmion device applications… read more. Open Access TECHNICAL ARTICLE
