Orbital occupancy and charge doping in iron-based superconductors
Claudia Cantoni, Jonathan E. Mitchell, Andrew F. May +9
Iron-based superconductors (FBS) comprise several families of compounds having the same atomic building blocks for superconductivity, but large discrepancies among their physical p…
Tuning the magnetic and structural phase transitions of PrFeAsO via Fe/Ru spin dilution
Yuen Yiu, Pietro Bonfà, Samuele Sanna +5
Neutron diffraction and muon spin relaxation measurements are used to obtain a detailed phase diagram of Pr(Fe,Ru)AsO. The isoelectronic substitution of Ru for Fe acts effectively…
A direct probe of the variability of Coulomb correlation in Fe-pnictide superconductors
P. Vilmercati, C. Parks Cheney, F. Bondino +9
We use core-valence-valence (CVV) Auger spectra to probe the Coulomb repulsion between holes in the valence band of Fe pnictide superconductors. By comparing the two-hole final sta…
Itinerant electrons, local moments, and magnetic correlations in pnictides high temperature superconductors
P. Vilmercati, A. Fedorov, F. Bondino +11
A direct and element-specific measurement of the local Fe spin moment has been provided by analyzing the Fe 3s core level photoemission spectra in the parent and optimally doped Ce…
Evolution of the nuclear and magnetic structures of TlFe1.6Se2 with temperature
Huibo Cao, Claudia Cantoni, Andrew F. May +6
The evolution of the nuclear and magnetic structures of TlFeSe was determined in the temperature range of 5-450\,K using single crystal neutron diffraction. The Fe laye…
Control of Correlations in Sr4V2O6Fe2As2 by Chemical Stoichiometry
Athena S. Sefat, David J. Singh, V. Ovidiu Garlea +4
We show using a combination of powder X-ray and neutron diffraction, first principles calculations, temperature- and field-dependent magnetization, heat capacity and resistivity da…
