In this work we present a study of the pinning field and coercivity of electrodeposited soft magnetic (Co76P24/Co85P15)N multilayered films. For f1kHz, a linear dependence of pinning field on N is reported, linear dependence which is valid as long as the films do not have a perpendicular contribution to the magnetic anisotropy. This behavior can be associated to the pinning of domain walls in the interfaces between the layers. For f>1kHz, the magnetic behavior is controlled by eddy currents, being the dependence of coercivity on frequency independent of N.
