Spin fluctuations away from (π,0) in the superconducting phase of molecular-intercalated FeSe
Physical Review B - Condensed Matter and Materials Physics 87:22 (2013)
Abstract:
Magnetic fluctuations in the molecular-intercalated FeSe superconductor Lix(ND2)y(ND3)1-yFe2Se2 (Tc=43K) have been measured by inelastic neutron scattering from a powder sample. The strongest magnetic scattering is observed at a wave vector Q≈1.4 Å-1, which is not consistent with the (π,0) nesting wave vector that characterizes magnetic fluctuations in several other iron-based superconductors but is close to the (π,π/2) position found for AxFe2-ySe2 systems. At the energies probed (∼5kBTc), the magnetic scattering increases in intensity with decreasing temperature below Tc, consistent with the superconductivity-induced magnetic resonance found in other iron-based superconductors. © 2013 American Physical Society.Crystal field states in a Quantum Spin Ice]{Crystal field states of Pr$^{3+}$ in the candidate quantum spin ice Pr$_{2}$Sn$_{2}$O$_{7}$
