  Single-crystal sample of chromium doped with ca.0.2 at.%119Sn was studied by
means of a transmission M\"ossbauer spectroscopy in the temperature range of
310-315 K. An anomaly in the temperature behavior of the center shift was found
at ca. 313 K, a temperature that coincides well with the N\'eel temperature of
chromium. The anomaly gives evidence that the vibrations of atoms in the
studied system are affected by the magnetism.
