This study provides additional information to complement the magnetic phase diagram of the Cr1-xRux alloy system in the higher Ru content region where the spin-density-wave (SDW) magnetism becomes suppressed. Results from the neutron diffraction investigation on a Cr+15 at% Ru polycrystalline sample reveal that the SDW ordering is commensurate to the underlying crystallographic structure for all temperatures below the Néel temperature (TN). The Néel temperature determined from the temperature dependences of the (1 0 0) magnetic peak intensity and the longitudinal wave velocity give TN=228 K. This temperature is significantly lower than was concluded from magnetic susceptibility and electrical resistivity studies that gave TN=270 K.
