"Magneto-optical Kerr effect in perpendicularly magnetized (Co2Pt6) n/Pt(111) superstructure";
Physical Review B, 73 (2006), 054402-1 - 054402-6.

English abstract:
Perpendicular magnetism facilitates an increase of the storage density by a factor 2-8 as compared to
longitudinal recording. Besides the improved chemical and physical stability of Co/Pt superstructures compared
to RE-TM alloys, a perpendicular easy axis can be obtained by selecting a suitable Co/Pt bilayer
thickness ratio. For different repetition numbers n 6 ab initio calculated Kerr angles are presented for
Co2Pt6 n superstructures on Pt 111 with a 6 Pt layers thick cap in a photon energy range of 1-8 eV. The
calculated maximum in the Kerr rotation angle occurs at an energy close to the experimentally observed value.
Assuming an exponential decay of the gradient of K with respect to n, an extrapolation of the calculated data
to large n was performed in order to compare the obtained results to available experimental data.
