Аннотация: The evolution of the structural and magnetic properties in epitaxial film systems Co/Pt(111) of equiatomic composition during vacuum annealing has been presented. Annealing to the temperature of 400A degrees C does not lead to the variation of the structural and magnetic properties of the films, which indicates the absence of consiПоказать полностьюderable mixing of the Co/Pt interface. With the increase in the annealing temperature from 400 to 750A degrees C, nanoclusters containing the main magnetically hard L1(0)CoPt(111) phase epitaxially intergrown with the CoPt3 phase are formed. High rotatable magnetic anisotropy has been found in the prepared films. In magnetic fields above the coercive force (H > H (C) = 8 kOe), the easy anisotropy axis with the angle of lag taken into account can be oriented in any spatial direction. Possible mechanisms of the formation of the rotatable magnetic anisotropy have been discussed. It has been assumed that the high rotatable magnetic anisotropy makes the main contribution to the magnetic perpendicular anisotropy in Co (x) Pt1-x films.
