A ferroelectric-like structural transition in a metal
Youguo Shi, Yanfeng Guo, Xia Wang +13
Metals cannot exhibit ferroelectricity because static internal electric fields are screened by conduction electrons, but in 1965, Anderson and Blount predicted the possibility of a…
Unconventional charge-density wave in Sr3Ir4Sn13 cubic superconductor revealed by optical spectroscopy study
A. F. Fang, X. B. Wang, P. Zheng +1
Sr3Ir4Sn13 is an interesting compound showing a coexistence of structural phase transition and superconductivity. The structural phase transition at 147 K leads to the formation of…
Revealing multiple density wave orders in non-superconducting titanium oxypnictide NaTiAsO
Y. Huang, H. P. Wang, R. Y. Chen +4
We report an optical spectroscopy study on the single crystal of NaTiAsO, a sister compound of superconductor BaTiSbO. The study reveals unexpectedly two densit…
Superconducting energy gap versus pseudogap in hole-doped cuprates as revealed by infrared spectroscopy
T. Dong, F. Zhou, N. L. Wang
We present in-plane infrared reflectance measurement on two superconducting cuprates with relatively low T: a nearly optimally-doped BiSrLaCuO with…
Effect of disorder in the charge-density-wave compounds LaTe and CeTeSe (x=0 and 0.16) as revealed by optical spectroscopy
Y. Huang, B. F. Hu, T. Dong +3
We present optical spectroscopy measurements on rare-earth ditelluride single crystals of LaTe and CeTeSe (x=0 and 0.16). The measurements reveal formation…
Continuous magnetic phase transition in half-frustrated Ca2Os2O7
P. Zheng, Y. G. Shi, Q. S. Wu +8
We present the specific heat, magnetization, optical spectroscopy measurements and the firstprinciple calculations on the Weberite structure Ca2Os2O7 single crystal/polycrystalline…
