Inhomogeneity of charge density wave order and quenched disorder in a high Tc superconductor
G. Campi, A. Bianconi, N. Poccia +11
It has recently been established that the high temperature (high-Tc) superconducting state coexists with short-range charge-density-wave order and quenched disorder arising from do…
Networks of superconducting nano-puddles in 1/8 doped YBa2Cu3O6.5+y controlled by thermal manipulation
Alessandro Ricci, Nicola Poccia, Gaetano Campi +8
While it is known that the nature and the arrangement of defects in complex oxides have an impact on the material functionalities little is known on control of superconductivity by…
Scanning micro X-ray diffraction unveils the distribution of oxygen chains nano-puddles in YBa2Cu3O6.33
Gaetano Campi, Alessandro Ricci, Nicola Poccia +5
Oxygen chain fragments are known to appear at the insulator to superconductor transition (SIT) in YBa2Cu3O6+y. However the self organization and the size distribution of oxygen cha…
Nanoscale phase separation in the iron chalcogenide superconductor K0.8Fe1.6Se2 as seen via scanning nanofocused x-ray diffraction
A. Ricci, N. Poccia, G. Campi +11
Advanced synchrotron radiation focusing down to a size of 300 nm has been used to visualize nanoscale phase separation in the K0.8Fe1.6Se2 superconducting system using scanning nan…
Intrinsic phase separation in superconducting K0.8Fe1.6Se2 (Tc= 31.8 K) single crystals
Alessandro Ricci, Nicola Poccia, Boby Joseph +9
Temperature dependent single-crystal x-ray diffraction (XRD) in transmission mode probing the bulk of the newly discovered K0.8Fe1.6Se2 superconductor (Tc = 31.8 K) using synchrotr…
Structural phase transition and superlattice misfit strain of RFeAsO (R = La, Pr, Nd and Sm)
Alessandro Ricci, Nicola Poccia, B. Joseph +9
The tetragonal-to-orthorhombic structural phase transition (SPT) in LaFeAsO (La-1111) and SmFeAsO (Sm-1111) single crystals measured by high resolution x-ray diffraction is found t…
