Room-temperature skyrmions appear in synthetic antiferromagnets

Researchers at the CNRS/Thales/Paris-Sud University led by Nicolas Reyren, Vincent Cros and Albert Fert are the first to have succeeded in stabilizing antiferromagnetic skyrmions in an ordinary material system at room temperature. The new result, reported in Nature Materials 10.1038/s41563-019-0468-3, will be important…
