Orphan spins and bound in-gap states in the antiferromagnet CaFeO
C. Stock, E. E. Rodriguez, N. Lee +11
CaFeO is an anisotropic antiferromagnet with two competing () and ($\uparrow \downarrow \uparrow \downar…
Spin-Lattice Coupling in K0.8Fe1.6Se2 and KFe2Se2: Inelastic Neutron Scattering and ab-initio Phonon Calculations
R. Mittal, M. K. Gupta, S. L. Chaplot +6
We report measurements of the temperature dependence of phonon densities of states in K0.8Fe1.6Se2 using inelastic neutron scattering technique. While cooling down to 150 K, a phon…
Pressure dependence of the low- temperature crystal structure and phase transition behaviour of CaFeAsF and SrFeAsF: A synchrotron x-ray diffraction study
S. K. Mishra, R. Mittal, S. L. Chaplot +8
We report systematic investigation of high pressure crystal structures and structural phase transition upto 46 GPa in CaFeAsF and 40 GPa in SrFeAsF at 40 K using powder synchrotron…
Ab initio lattice dynamics simulations and inelastic neutron scattering spectra for studying phonons in BaFe2As2: Effect of structural phase transition, structural relaxation and magnetic ordering
M. Zbiri, H. Schober, M. R. Johnson +5
We have performed extensive ab initio calculations to investigate phonon dynamics and their possible role in superconductivity in BaFe2As2 and related systems. The calculations are…
