摘要

Ternary silicides A(Ga-x,Si1-x)(2) (A = Ca, Sr, and Ba) were prepared by Ar are melting. Powder X-ray diffraction indicates that they have the AlB2-type structure in which Si and Ga atoms are arranged in chemically disordered honeycomb layers and atoms A are intercalated between them. Resistivity and DC magnetization measurements revealed that they are superconductors with a critical temperature for superconductivity ranging from 3.3 to 3.9 K. (C) 2001 Elsevier Science B.V.
