High-Pressure Synthesis of Superconducting YSr2Cu3Oy
TLDR
In this article, a tetragonal "1-2-3" type was synthesized as a superconductor with an onset temperature of 60 K, where a and c are 3.7949 and 11.4102 A, respectively.Abstract:
At a high oxygen pressure of 7 GPa and high temperature of 1380°C, YSr2Cu3Oy was synthesized as a single phase. The crystal structure is a tetragonal "1-2-3" type, where a and c are 3.7949 A and 11.4102 A, respectively. This material is a superconductor with an onset temperature of 60 K.read more

Synthesis and superconducting properties of the strontium copper oxy-fluoride Sr2CuO2F2+δ
TL;DR: In this paper, the structural changes previously initiated by the thermodynamic effects of high pressure are induced chemically under ambient conditions, resulting in a superconducting oxy-fluoride in which fluorine plays a dominant structural role, rather than merely being an electronic dopant.
