Isomorphs of the superconducting/magnetic ternary stannides

Abstract

Single crystals of some new ternary stannides in the systems (M)CoSn, (M)RuSn and (M)OsSn, where M = rare earth, Y. Sc, Ca, Sr, or Th have been grown from a tin solvent in vacuo. We find the new compounds to be isomorphous to the published rare earth rhodium tin compounds. The ternary, TmOsxSny, has been found to be a reentrant superconductor with Tc = 1.1K and Tm = 0.6K. Superconducting and/or magnetic transition temperatures and lattice parameters are given. A tabular summary of identified phases and their lattice constants for all the ternary stannides prepared so far is included for comparative purposes. © 1982.
