Abstract

Novel Ternary Compound Ce 2 RuAl: Synthesis, Crystal Structure, Magnetic and Electrical Properties. -Intermetallic Ce2RuAl is prepared by arc melting of the elements followed by annealing at 823 K. Single crystal XRD data show that the compound is of a new structural type related to the LaF3-type (space group P63cm, Z = 6). Some Ce-Ru distances in the unit cell are unusually short with 2.4821 Å. This structural feature causes instability in the Ce valence state which is directly evidenced by XANES data and also expressed in temperature-dependent magnetic susceptibility and electrical resistivity data. -(MURASHOVA*, E.; KURENBAEVA, Z.; TURSINA, A.; MARUSHINA, E.; YAROSLAVTSEV, A.; LESHCHEV, D.; SEROPEGIN, Y.; KACZOROWSKI, D.; J.
