Co atoms on Bi${}_2$Se${}_3$ revealing a coverage dependent spin reorientation transition

T. Eelbo, M. Sikora, G. Bihlmayer +4

We investigate Co nanostructures on Bi${}_2$Se${}_3$ by means of scanning tunneling microscopy and spectroscopy [STM/STS], X-ray absorption spectroscopy [XAS], X-ray magnetic dichr…
