Abstract
Magneto-optical measurements of the anisotropy of homogeneous Dy18Fe82 films as a function of thickness (134.0-13.4 nm) confirm that the per pendicular anisotropy disappears when films are less than 60nm thick S ince, the range of films exhibits both out of plane and in-plant aniso tropy, both the polar Kerr effect and the transverse Kerr effect were used to determine the anisotropy, At about 60nm the perpendicular anis otropy K-perpendicular to less than or equal to the shape anisotropy ( K-s=2 pi M-s(2)).
