Stabilization of charge and orbital ordered states by antiferromagnetism in the A-site ordered YBaMn2O6
X. N. Zhang, K. -Y. Choi, P. Lemmens +2
We report on Raman scattering measurements of the A-site ordered YBaMn2O6 in the wide temperature range of 10-650K. Upon cooling almost all phonon modes show pronounced temperature…
Self-energy effects and electron-phonon coupling in Fe-As superconductors
K. -Y. Choi, P. Lemmens, I. Eremin +5
We report on Raman scattering experiments of the undoped SrFe2As2 and superconducting Sr0.85K0.15Fe2As2 (Tc=28K) and Ba0.72K0.28Fe2As2 (Tc=32K) single crystals. The frequency and l…
Two inequivalent sublattices and orbital ordering in MnV2O4 studied by 51V NMR
S. -H. Baek, N. J. Curro, K. -Y. Choi +4
We report detailed 51V NMR spectra in a single crystal of MnV2O4. The vanadium spectrum reveals two peaks in the orbitally ordered state, which arise from different internal hyperf…
Iron pnictides: Single crystal growth and effect of doping on structural, transport and magnetic properties
G. L. Sun, D. L. Sun, M. Konuma +6
We demonstrate the preparation of large, free standing iron pnictide single crystals with a size up to 20 x 10 x 1 mm3 using solvents in zirconia crucibles under argon atmosphere.…
