Abstract
Biharmonic pumping technique was used to study four-photon nonlinear respon se of ultrathin ferromagnetic metal films (Ni, thickness down to 17 nm) and some reference samples (Bi and Au). In the case of Ni films, we found spec ific two-photon resonant feature on a side wing of dependence of self-diffr action efficiency versus frequency detuning of biharmonic pumping component s. We interpret this feature as a manifestation of Ni ferromagnetism.
