Inelastic electron tunneling spectra of Pb/MnPSe 3 /Pb junctions are measured below liquid helium temperature in the normal state of lead under an external magnetic field. The insulating barrier of MnPSe 3 , an antiferromagnetic layered transition metal phosphorous triselenide, is cleaved from a single crystal along the layer. The spectra are explained by interactions between tunneling electrons and MnPSe 3 antiferromagnetic magnons as well as those between tunneling electrons and MnPSe 3 phonons. The contribution of MnPSe 3 magnons to inelastic processes is comparable to that of MnPSe 3 phonons.
