摘要：

A new non-Cu superconductor (Sr1-xLn(x))Nb2O6-y(Ln: La, Nd, Pr, Ce, Gd and Ho) has been found through resistivity and magnetization measurements. The highest onset transition temperature is about 12 K. Preliminary electron and X-ray diffraction experiments indicate that the crystal structure of the system is orthorhombic with a unit cell of a = 11.00 angstrom, b = 7.68 angstrom and c = 5.59 angstrom, suggesting that the basic crystal structure is an oxygen-deficient CaTa2O6-type structure.
