Mn/Cu(111): alloying, electronic and magnetic properties

Spin-split two-dimensional (2D) states which can, for instance, be realized in magnetically stabilized surface alloys, are of immense technological interest for new spintronic devices. We have studied the interaction of manganese with a Cu(111) surface using different surface sensitive techniques. STS at low temperature indicates no observable Kondo-effect for single Mn atoms. Formation of the surface alloy first leads to the quenching of the Cu(111) surface state. Our results indicate none or very weak magnetic and spin-splitting effects for Mn/Cu(111).
