Can I read 50 K enhancement of Tc by pressure in the Hg-2212 superconductor on EtoBox?
50 K enhancement of Tc by pressure in the Hg-2212 superconductor by C Acha; S.M Loureiro; C Chaillout; J.L Tholence; J.J Capponi; M Marezio; M Núñez-Regueiro is a Physics and Astronomy article available to read on EtoBox.
What is 50 K enhancement of Tc by pressure in the Hg-2212 superconductor about?
The superconducting properties of mercury cuprates are extremely sensitive to compression. The highest transition temperatures obtained up to date have been measured on Hg-1223 at 25-30 Gpa (TC -164 K at the onset) and imply an increase of about 20 K with respect to the ambient pressure TCo. We report here the largest total pressure effect ( > 50 K over a span of 20 GPa) ever observed for several samples of bi-mercury layer Hg2Ba2(Y1 \_$Zax)Cu20a-6 compositions. Different Ca doping levels give different initial T,s but retain the same strong pressure dependence. The large T, increase with pressure for all the Hg-based compounds, independently of their doping level, is revealing the existence of a common structural parameter, which identification will be a guide for future synthesis efforts of record-high T, materials.
