Abstract

We have recently reported the d1 square-lattice compound BaTi2Sb2O, which shows superconductivity at Tc = 1.2K coexisting with a charge- or spin-density wave (CDW/SDW) state. Here, we successfully prepared two new oxybismuthides, BaTi2Bi2O and (SrF)2Ti2Bi2O, as the first Pn = Bi compounds in the ATi2Pn2O family. The CDW/SDW state disappeared for both compounds, presumably owing to the considerable interaction between the Ti-3d and Bi-6s orbitals. The complete suppression of the CDW/SDW instability resulted in an enhanced Tc of 4.6K for BaTi 2Bi2O. However, (SrF)2Ti2Bi 2O exhibits no superconductivity, suggesting the importance of the interlayer interaction for superconductivity. © 2013 The Physical Society of Japan.
