Notes:
Transverse biased initial susceptibility (TBIS) measurements were made using a magneto-optical Kerr effect system on samples that exhibited an in-plane and a perpendicular anisotropy. A change in the slope of both the inverse transverse susceptibility and the hysteresis loop is observed at a certain value of the applied in-plane field Hs. At values of the applied field higher than Hs the magnetization lies in the plane of the film; at values lower than Hs an out-of-plane component appears. By performing TBIS measurements we can also detect different micromagnetic phases magnetically uncoupled with different values of the anisotropy field. The occurrence of a downwards curvature in the inverse susceptibility when the dc field is applied along the hard axis together with the multiple minima when the dc field is applied along the easy axis can be explained by the existence of weakly coupled micromagnetic phases. © 1996 American Institute of Physics.
