In this paper inelastic electron tunneling spectroscopy measurements are presented on tunnel junctions containing both magnetic and nonmagnetic electrodes. Magnon excitations have been found near zero voltage; phonons are observed between 30 and 110 mV. Therefore, a model description of the transport properties of magnetic tunnel junctions at elevated temperatures or non-zero bias voltage should include both inelastic contributions.
