Abstract：

Motivated　by　advances　in　spintronic　devices,　extensive　explorations　are　underway　to　uncover　materials　that　host　topologically　protected　spin　textures,　exemplified　by　skyrmions.　One　critical　challenge　involved　in　the　potential　application　of　skyrmions　in　van　der　Waals　(vdW)　materials　is　the　attainment　and　manipulation　of　skyrmions　at　room　temperature.　In　this　study,　we　report　the　creation　of　an　intrinsic　skyrmion　state　in　the　van　der　Waals　ferromagnet　Fe3GaTe2.　By　employing　variable　temperature　magnetic　force　microscopy,　the　skyrmion　lattice　can　be　locally　manipulated　on　Fe3GaTe2　flakes.　The　ordering　of　skyrmion　state　is　further　analyzed.　Our　results　suggest　Fe3GaTe2　emerges　as　a　highly　promising　contender　for　the　realization　of　skyrmion-based　layered　spintronic　memory　devices.　©　2024　The　Authors
