Py150Å/Cr70Å/Co 200Å/Cr150Å sputtered Sims deposited on glass were studied by means of magneto-optical Kerr effect and planar Hall effect. The properties of these films are dominated by the Co layer which exhibits not only uniaxial in-plane anisotropy but, also a very hard magnetization component which is canted out of the film plane. A striking feature of the angular dependence of hysteresis loops is the apparent loss of two-fold symmetry. Due to the out of plane magnetization, the Hall voltage signal comprises not only the planar Hall but also the ordinary and extraordinary Hall effect signals.
