TL;DR: New high-T{c} Fe-based superconducting compounds, AFe2As2 with A=K, Cs, K/Sr, and Cs/SR, were synthesized, and their electronic and structural behavior demonstrate the crucial role of the (Fe2 as2) layers in the superconductivity of the Fe- based layered systems.

TL;DR: The superconducting transition temperatures of optimally doped Hg 1:2:m-1:m with m=1, 2, and 3 were investigated resistively under quasihydrostatic pressures up to 45 GPa.

TL;DR: In this paper, the authors reported superconductivity at up to 153 K in Hg-1223 at 150 kbar, with a main transition at 147 K. This observation provides an indication that supercondivity at >150 K may be possible in this system at ambient pressure, if suitable forms of chemical substitution can be found.

TL;DR: Anomalies in the dielectric constant and loss tangent have been observed in the ferroelectromagnet YMnO{sub 3} near its N{acute e}el temperature of {approximately}80 K and below its ferroelectric Curie temperature of{approximately}914 K as mentioned in this paper.

TL;DR: Stable superconductivity up to 114 K has been reproducibly detected in Bi-Al-Ca-Sr-Cu-O multiphase systems without any rare-earth elements, providing an extra material base for the study of the mechanism of high-temperaturesuperconductivity and also the prospect of reduced material cost for future applications of superconductor.
