Synthesis and Physical Properties of the New Oxybismuthides BaTi2Bi2O and (SrF)2Ti2Bi2O with a d^{1} Square Net

We have recently reported the \(d^{1}\) square-lattice compound BaTi2Sb2O, which shows superconductivity at \(T_{\text{c}} = 1.2\) K 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 \(A\)Ti2 Pn 2O 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 \(T_{\text{c}}\) of 4.6 K for BaTi2Bi2O. However, (SrF)2Ti2Bi2O exhibits no superconductivity, suggesting the importance of the interlayer interaction for superconductivity.

Upgrade of beamline BL25SU for soft x-ray imaging and spectroscopy of solid using nano- and micro-focused beams at SPring-8

Substantial upgrades have been made to the beamline BL25SU at SPring-8 for soft X-ray imaging and spectroscopy of solid-state materials. The upgraded beamline consists of two branches: a micro-beam branch with high energy resolution, and a nano-beam branch with small angular divergence. The beamline has been available for use since October 2014, following a half year commissioning period. We present here the beamline performance parameters, including resolving power, photon flux, and focused beam size, which are consistent with designed specifications.
