The influence of the bilinear and biquadratic coupling on the exchange anisotropy of the ferromagnetic/antiferromagnetic bilayer was studied by variable angle and temperature dependent ferromagnetic resonance. From the angular dependence of the resonance field the bilinear and biquadratic exchange coupling constants were determined.
