The study results of the tunnel conductance of heterostructures formed by a silver tip and a doped Ag/La₀.₅₇Ca₀.₄₃MnO₃ manganite in the voltage region above manganite phonon and magnon frequencies are presented. Three maxima have been observed at energies corresponding to the peaks in the Raman spec...
