Soft x-rays absorption and high-resolution powder x-ray diffraction study of superconducting CaxLa(1-x)Ba(1.75-x)La(0.25+x)Cu3Oy system
S. Agrestini, S. Sanna, K. Zheng +5
We have studied the electronic structure of unoccupied states measured by O K-edge and Cu L-edge x-ray absorption spectroscopy (XAS), combined with crystal structure studied by hig…
Anisotropic Exchange Interaction between Non-magnetic Europium Cations in Eu_2O_3
G. Concas, J. K. Dewhurst, A. Sanna +2
The electronic structure of the cubic and (high pressure) hexagonal phases of Eu2O3 have been investigated by mean of full potential linearized augmented plane wave calculations, w…
Competing orders suppressed by disorder around a hidden quantum critical point in cuprate high Tc superconductors
S. Sanna, F. Coneri. A. Rigoldi, G. Concas +2
We report extensive muon spin rotation measurements on the lightly doped Y1-xCaxBa2Cu3O6+y compound, which allows us to disentangle the effect of disorder, controlled by random Ca2…
Evidence of two distinct charge carriers in underdoped high Tc cuprates
S. Sanna, F. Coneri, A. Rigoldi +2
We present results on heavily underdoped Y_1-xCa_xBa_2Cu_3O_6+y which provide the evidence that the doping mechanism (cation substitution or oxygen loading) directly determines whe…
Search for non-Poissonian behavior in nuclear beta-decay
Giorgio Concas, Marcello Lissia
We performed two independent counting experiments on a beta-emitting source of Sm151 by measuring the gamma-photon emitted in a fraction of the decays. For counting times ranging f…
