Possible origin of high Tc superconductivity
A mechanism to explain high-T c superconductivity, based on the double-well motion of the oxygen ions in such systems, is extended to predict T c values of for (La, Ba) 2 CuO 4 and Ba 2 Cu 3 O 7 . This gives lower bounds on T c of 53K for the former and 44K for the latter. Since the second number, i...
