Temperature-activated valence fluctuation has been concluded in a semiconducting compound Sm3Se4 from detailed temperature- and frequency-dependencies of the nuclear relaxation rates of 77Se NMR above about 130 K. Exploiting the different time-window of the μ+SR technique, the valence fluctuation in the lower-temperature range and the ground-state magnetic properties have also been investigated.
