The phase composition at room temperature and the magnetization up to 55 kOe over the temperature interval 5-400 K for polycrystalline compounds YCo3+delta (- 0.18 less than or equal to delta less than or equal to 0.24) and Y(Co1-xAlx)(2.92) (x less than or equal to 0.1) were studied. It was found that a homogeneous rhombohedral PuNi3-type structure is formed within the Co concentration interval -0.14 less than or equal to delta < -0.08. The magnetic ordering temperature, magnetization at 5.5 T, and the lattice parameters of YCo2.88, were determined to be 260+/-2 K, 0.46+/-0.3 mu(B)/Co and a = 5.02 Angstrom, c = 24.38 Angstrom (hexagonal set), respectively. The nonlinear variation of T-C vs. Al concentration was ascribed to the composition dependence of the Co magnetic moment. (C) 2000 Elsevier Science S.A. All rights reserved.
