Abstract

The thermal annealing of Co/Pt(1 1 1) ultrathin films at appropriate temperatures results in a kind of Co-Pt alloy formation at the interface. This, in turn, gives rise to a large enhancement of magnetooptical Kerr response up to about 300% and an increase in perpendicular magnetic anisotropy. The highly-enhanced magnetooptical response is believed to be mainly attributed to the transfer of the strong spin-orbit coupling of the Pt into the Co caused by the hybridized electronic state at the alloying interface.
