Local structure of REFeAsO (RE=La, Pr, Nd, Sm) oxypnictides studied by Fe K-edge EXAFS
A. Iadecola, S. Agrestini, M. Filippi +5
Local structure of REOFeAs (RE=La, Pr, Nd, Sm) system has been studied as a function of chemical pressure varied due to different rare-earth size. Fe K-edge extended X-ray absorpti…
Experimental evidence of chemical-pressure-controlled superconductivity in cuprates
S. Sanna, S. Agrestini, K. Zheng +2
X-ray absorption spectroscopy (XAS) and high resolution X-ray diffraction are combined to study the interplay between electronic and lattice structures in controlling the supercond…
Study of temperature dependent atomic correlations in MgB
G. Campi, E. Cappelluti, Th. Proffen +6
We have studied the evolution with temperature of the local as well as the average crystal structure of MgB using the real-space atomic pair distribution function (PDF) measure…
Sc substitution for Mg in MgB2: effects on Tc and Kohn anomaly
S. Agrestini, C. Metallo, M. Filippi +9
Here we report synthesis and characterization of Mg_{1-x}Sc_{x}B_{2} (0.12<x<0.27) system, with critical temperature in the range of 30>T_{c}>6 K. We find that the Sc doping moves…
