Magnetic structure and orbital ordering in KCrF3 perovskite
Y. Xiao, Y. Su, H. -F. Li +6
KCrF3 represents another prototypical orbital-ordered perovskite, where Cr2+ possesses the same electronic configuration of 3d4 as that of strongly Jahn-Teller distorted Mn3+ in ma…
Suppression of superconductivity by V-doping and possible magnetic order in Sr2VO3FeAs
Marcus Tegel, Tanja Schmid, Tobias Stürzer +4
Superconductivity at 33 K in Sr2VO3FeAs is completely suppressed by small amounts of V-doping in Sr2VO3[Fe0.93(+/-0.01)V0.07(+/-0.01)]As. The crystal structures and exact stoichiom…
Helical spin-waves, magnetic order, and fluctuations in the langasite compound Ba3NbFe3Si2O14
C. Stock, L. C. Chapon, A. Schneidewind +6
We have investigated the spin fluctuations in the langasite compound Ba3NbFe3Si2O14 in both the ordered state and as a function of temperature. The low temperature magnetic structu…
Magnetic Lattice Dynamics of the Oxygen-Free FeAs Pnictides: How Sensitive are Phonons to Magnetic Ordering?
Mohamed Zbiri, Ranjan Mittal, Stephane Rols +10
To shed light on the role of magnetism on the superconducting mechanism of the oxygen-free FeAs pnictides, we investigate the effect of magnetic ordering on phonon dynamics in the…
Synchrotron X-ray Diffraction Study of BaFe2As2 and CaFe2As2 at High Pressures up to 56 GPa: Ambient and Low-Temperatures Down to 33 K
R. Mittal, S. K. Mishra, S. L. Chaplot +9
We report high pressure powder synchrotron x-ray diffraction studies on MFe2As2 (M=Ba, Ca) over a range of temperatures and pressures up to about 56 GPa using a membrane diamond an…
Magnetic correlations in spin ice Ho2-xYxTi2O7 as revealed by neutron polarization analysis
L. J. Chang, Y. Su, Y. -J. Kao +6
We present single-crystal neutron-diffuse-scattering measurements with polarization analysis on the spin ice Ho2-xYxTi2O7 (x = 0, 0.3, and 1). At 2 K, the spin flip scattering patt…
