In this study, we fabricate molecular magnetic tunnel junctions and demonstrate that inelastic electron tunneling spectroscopy technique can be utilized to inspect such junctions to investigate the existence of desired molecular species in the device area. Tunneling magnetoresistance measurements have been carried out and spin‐dependent tunneling transport has been observed. Bias‐dependence of the tunneling resistance has also been detected. IETS measurements at different magnetic field suggested that the TMR bias‐dependence was likely caused by the inelastic scattering due to the molecular vibrations.
