Abstract

This study provides additional information to complement the magnetic phase diagram of the Cr_1-xRu_x 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 (T_N). The Néel temperature determined from the temperature dependences of the (1 0 0) magnetic peak intensity and the longitudinal wave velocity give T_N=228 K. This temperature is significantly lower than was concluded from magnetic susceptibility and electrical resistivity studies that gave T_N=270 K.
