N2 - We report the structure and magnetic investigations of the quasiternary UCo1-xRuxAl compounds crystallizing in the hexagonal structure of the ZrNiAl type. A large deviation from linearity is observed in the concentration dependence of lattice parameters, positive for a and negative for c, whereas the unit-cell volume V obeys Vegard's law satisfactorily. The nonlinearity is explained by a preferential occupation by the Co and Ru atoms of the two non-equivalent positions of the transition metal in the lattice. Although UCoAl and URuAl are paramagnetic down to low temperatures, ferromagnetism is observed in a wide concentration range of quasiternary solid solutions UCo1-xRuxAl. Both the Curie temperature and the spontaneous magnetization reach their maximum values of 60 K and 0.6μB (formula unit)−1 respectively in UCo0.7Ru0.3Al.
