Surface magnetometry with photoemission dichroism: Ultrathin epitaxial Fe-Co bcc alloys on Fe(100)

Abstract

The merits of magnetic dichroism in photoemission as a surface magnetometer are evaluated by performing a systematic investigation of the linear magnetic dichroism in the angular distribution (LMDAD) effect on the Fe $3p$ and Co $3p$ photoemission signal from ultrathin bcc Fe-Co alloys epitaxially grown onto Fe(100).
