Abstract
A systematic X-ray investigation of the ternary YRhSi system has been carried out to obtain new materials with possible superconducting properties. Y 3Rh 2Si 2 is made up of Y and Si trigonal prisms centred by Si and Rh atoms and can be derived from an hexagonal close-packed model using the concept of unit-cell twinning. Moreover, members of a structural series R n + 2 T 2Si n + 2 (R ≡ rare earth, T ≡ transition metal) were obtained: Y 3RhSi 3, ( n = 4), Y 2RhSi 2 ( n = 2) and Y 3Rh 2Si 3 ( n = 1). Their structures are made up of bands of n infinite columns of trigonal prisms connected by two infinite columns of Y and Rh trigonal prisms. All prisms are Si centered. Members of another structural series, R n + 2 T 3 n + 3 Si 2 n + 1 were also obtained: YRh 2Si ( n = 1) and Y 4Rh 9Si 5 ( n = 2). Both structures are built up with Mg 2Cu 3Si-type and CeCo 3B 2-type slabs. YRh 2Si is an ordered version of the hexagonal CeNi 3 structure and Y 4Rh 9Si 5 is an ordered version of the rhombohedral Gd 2Co 7 structure. Electrical resistivity and magnetic susceptibility measurements were made for these compounds.
