We report the first experimental observation of the longitudinal resonance mode whose existence for ferromagnets with random anisotropy was predicted by theoretical computations. It could be detected in (RE = Pr, Nd, Tb and Dy) amorphous thin films, when these films exhibit an in-plane uniaxial anisotropy field Hk. Hk imposes the "ferromagnet with wandering axis” regime. The formal experimental identification of the longitudinal nature of the mode, and its main properties, resonance field, resonance linewidth, are presented and compared with theoretical predictions.
