Bound state of 4-excitation and magnetic resonance in unconventional superconductors
Alireza Akbari, Ilya Eremin, Peter Thalmeier +1
We analyze the influence of unconventional superconductivity on crystalline electric field (CEF) excitations of rare earth ions in novel superconductors. We show that resonant magn…
Theory of Raman response in a superconductor with extended s-wave symmetry: Application to Fe-pnictides
Andrey V. Chubukov, Ilya Eremin, Maxim M. Korshunov
We argue that Raman study of Fe-pnictides is a way to unambiguously distinguish between various superconducting gaps proposed for these materials. We show that Raman inten…
Non-analytic spin susceptibility of a nested Fermi liquid: the case of Fe-based pnictides
M. M. Korshunov, I. Eremin, D. V. Efremov +2
We propose an explanation of the peculiar linear temperature dependence of the uniform spin susceptibility in ferropnictides. We argue that the linear in term appears du…
Electronic properties of LaOFFeAs in the normal state probed by NMR/NQR
H. -J. Grafe, G. Lang, F. Hammerath +12
We report 139La, 57Fe and 75As nuclear magnetic resonance (NMR) and nuclear quadrupole resonance (NQR) measurements on powders of the new LaO1-xFxFeAs superconductor for x = 0 and…
Lattice and electronic anomalies of CaFe_2As_2 studied by Raman spectroscopy
K. -Y. Choi, D. Wulferding, P. Lemmens +3
We report inelastic light scattering experiments on CaFe_2As_2 in the temperature range of 4 to 290 K. In in-plane polarizations two Raman-active phonon modes are observed at 189 a…
Doping evolution of itinerant magnetic excitations in Fe-based oxypnictides
M. M. Korshunov, I. Eremin
Employing the four-band tight-binding model we study theoretically the doping dependence of the spin response in the normal state of novel Fe-based pnictide superconductors. We sho…
