The once-created metastable skyrmions survive at zero magnetic field both at and above room temperature. Such robust skyrmions in a wide temperature and magnetic field region demonstrate the key role of topology and provide a significant step toward technological applications of skyrmions in bulk chiral magnets.Skyrmion formation in a bulk chiral magnet at zero magnetic field and above room temperaturetext::journal::journal article::research article
