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…
Energy and symmetry of excitations in undoped layered cuprates measured by Cu resonant inelastic x-ray scattering
M. Moretti Sala, V. Bisogni, C. Aruta +17
We measured high resolution Cu edge resonant inelastic x-ray scattering (RIXS) of the undoped cuprates LaCuO, SrCuOCl, CaCuO and NdBaCuO.…
Dispersing bimagnons and doping induced bimagnon-charge modes in superconducting cuprates
L. Braicovich, L. J. P. Ament, V. Bisogni +11
In the early days of high temperature superconductivity it was already recognized that magnetic properties of these materials are intimately related to the superconducting ones . W…
Observation of Spin Fluctuations in a High-Tc Parent Compound Using Resonant Inelastic X-ray Scattering
B. Freelon, P. G. Medaglia, A. Tebano +12
We report the first observation of soft-x-ray scattering from spin fluctuations in a high-Tc parent compound. An antiferromagnetic charge transfer insulator, CaCuO2, was irradiated…
Evidence of orbital reconstruction at interfaces in La0.67Sr0.33MnO3 films
A Tebano, C. Aruta, S. Sanna +8
Electronic properties of transition metal oxides at interfaces are influenced by strain, electric polarization and oxygen diffusion. Linear dichroism (LD) x-ray absorption, diffrac…
Dissipation in ultra-thin current-carrying superconducting bridges; evidence for quantum tunneling of Pearl vortices
F. Tafuri, J. R. Kirtley, D. Born +5
We have made current-voltage (IV) measurements of artificially layered high- thin-film bridges. Scanning SQUID microscopy of these films provides values for the Pearl lengths…
