N2 - A new non-Cu superconductor (Sr1-xLnx)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 A, & = 7.68 A and c = 5.59 A, suggesting that the basic crystal structure is an oxygen-deficient CaTa2O6-type structure.
