Times Cited Count:0 Percentile:0(Engineering, Electrical & Electronic)In this study, we employed a superconducting detector, current-biased kinetic-inductance detector (CB-KID) for neutron imaging using a pulsed neutron source. We employed the delay-line method, and high spatial resolution imaging with only four reading channels was achieved. We also performed wavelength-resolved neutron imaging by the time-of-flight method. We obtained the neutron transmission images of a Gd-Al alloy sample, inside which single crystals of GdAl were grown, using the delay-line CB-KID. Single crystals were well imaged, in both shapes and distributions, throughout the Al-Gd alloy. We identified Gd nuclei via neutron transmissions that exhibited characteristic suppression above the neutron wavelength of 0.03 nm. In addition, the Gd resonance dip, a dip structure of the transmission caused by the nuclear reaction between an isotope and neutrons, was observed even when the number of events was summed over a limited area of 15 m 12 m. Gd selective imaging was performed using the resonance dip of Gd, and it showed clear Gd distribution even with a limited neutron wavelength range of 1 pm.

Times Cited Count:21 Percentile:64.58(Materials Science, Multidisciplinary)Characteristic normal-state charge transport is found in the oxygen-deficient iron-arsenides FeAsO (: La and Nd) with the highest 's among known Fe-based superconductors. The effect of "doping" in this system is mainly on the carrier scattering, quite distinct from that in high- cuprates. In the superconducting regime of the La system with maximum = 28 K, the low-temperature resistivity is dominated by a term. On the other hand, in the Nd system with higher than 40 K, the carriers are subject to stronger scattering showing -linear resistivity and small magnetoresistance. Such strong scattering appears crucial for high- superconductivity in the iron-based system.

Times Cited Count:42 Percentile:79.26(Materials Science, Multidisciplinary)We investigate the effect of disorder at various lattice sites outside the CuO plane on the superconducting critical temperature of the cuprate superconductor BiSrCaCuO (Bi2212). The most effective disorder turns out to be that at the Sr site in the neighboring blocks, which contain apical-oxygen atoms.
