Raman spectroscopy study of the interface structure in (CaCuO2)n/(SrTiO3)m superlattices
D. Di Castro, S. Caramazza, D. Innocenti +4
Raman spectra of CaCuO2/SrTiO3 superlattices show clear spectroscopic marker of two structures formed in CaCuO2 at the interface with SrTiO3. For non-superconducting superlattices,…
Spectromicroscopy of electronic phase separation in KFeSe superconductor
M. Bendele, A. Barinov, B. Joseph +14
Structural phase separation in AFeSe system has been studied by different experimental techniques, however, it should be important to know how the electronic unifor…
Direct observation of nanoscale interface phase in the superconducting chalcogenide KFeSe with intrinsic phase separation
A. Ricci, N. Poccia, B. Joseph +13
We have used scanning micro x-ray diffraction to characterize different phases in superconducting KFeSe as a function of temperature, unveiling the thermal evolut…
CDW and similarity of the Mott-Insulator-to-Metal transition in cuprates with the gas to liquid-liquid transition in supercooled water
G. Campi, D. Innocenti, A. Bianconi
New advances in x-ray diffraction, extended x-ray absorption fine structure EXAFS and x-ray absorption near edge structure XANES using synchrotron radiation have now provided compe…
Heterogeneity and anomalous critical indices in the aftershocks distribution of L Aquila earthquake
D. Innocenti, M. Iovenitti, N. Poccia +3
The data analysis of aftershock events of L Aquila earthquake in Apennines following the main 6.3 Mw event of April 6, 2009 has been carried out by standard statistical geophysical…
Intermittent dynamics of antiferromagnetic phase in inhomogeneous iron-based chalcogenide superconductor
A. Ricci, G. Campi, B. Joseph +9
Coexistence of phases, characterized by different electronic degrees of freedom, commonly occurs in layered superconductors. Among them, alkaline intercalated chalcogenides are mod…
