Abstract
The high sensitivity of the magneto-optical Kerr effect to details of the electronic structure is used to identify a structural transition f rom fee to hcp in ultrathin Co(111) wedges on Pt(111). The variation o f the Kerr rotation with Co thickness yields two distinct regions: (i) fcc(111) Co in the range 0.4 < d(Co) < 1 nm and (ii) hcp(0001) Co in the range d(Co) > 1.2 nm. These regions show characteristic volume and interface magnetic anisotropies.
