High Tc superconductivity in superlattices of insulating oxides
D. Di Castro, M. Salvato, A. Tebano +13
We report the occurrence of superconductivity, with maximum Tc = 40 K, in superlattices (SLs) based on two insulating oxides, namely CaCuO2 and SrTiO3. In these (CaCuO2)n/(SrTiO3)m…

Intense paramagnon excitations in a large family of high-temperature superconductors
M. Le Tacon, G. Ghiringhelli, J. Chaloupka +17
In the search for the mechanism of high-temperature superconductivity, intense research has been focused on the evolution of the spin excitation spectrum upon doping from the antif…
