A dispersive two-branch structure in the magnetic excitation spectra is reported for mixed-valence Sm1-xYxS(0≤x≤0.33). This behavior is ascribed to Sm-Sm exchange interactions and discussed in connection with the possible formation of a local excitonic singlet ground state in this class of mixed-valence semiconductors.
