  The advent of long-range magnetic order in non-centrosymmetric compounds has
stimulated interest in the possibility of exotic spin transport phenomena and
topologically protected spin textures for applications in next-generation
spintronics. This work reports a novel wurtzite-structure polar magnetic metal,
identified as AA'-stacked (Fe0.5Co0.5)5-xGeTe2, which exhibits a Neel-type
skyrmion lattice as well as a Rashba-Edelstein effect at room temperature.
Atomic resolution imaging of the structure reveals a structural transition as a
function of Co-substitution, leading to the polar phase at 50% Co. This
discovery reveals an unprecedented layered polar magnetic system for
investigating intriguing spin topologies and ushers in a promising new
framework for spintronics.
