We investigated successive phase transitions in SmBC at =37K and =51K by means of resonant X-ray diffraction. Strong resonant diffraction signal is observed at the 101 reflection below at the Sm edge, whereas in the intermediate phase signals appear at incommensurate positions =(1, ,1) where =0.13. Accordingly, the successive phase transitions in SmBC is found to be commensurate-to-incommensurate magnetic phase transitions.
