Abstract

The magnetic properties of the ultrathin FeCoCu (100) films grown at 110 K with Co underlayer thickness below 2 monolayers (ML) are investigated by means of the in situ magneto-optical Kerr effect. The spin reorientation transitions (SRT) from out-of-plane to in-plane influenced by the Co underlayer are observed. A simplified bilayer growth mode of Co is introduced to fit the experiment results, obtaining that the true critical Fe thickness of a SRT if without structural transformation for a fct Fe on Cu(001) is about 4.6 ML, the same value as the previous Co capping experiment.
