Selective coupling of high-order phonons in La2-xSrxCuO4
Ke-Jun Xu, Paulina Majchrzak, Nathan Giles-Donovan +14
In crystals and molecules with strong coupling between the charge carriers and atomic vibrations, high order harmonics of the vibrational excitations can be observed with intensity…
Observation of a dispersive charge mode in hole-doped cuprates using resonant inelastic x-ray scattering at the oxygen K edge
K. Ishii, T. Tohyama, S. Asano +13
We investigate electronic excitations in La2-x(Br,Sr)xCuO4 using resonant inelastic x-ray scattering (RIXS) at the oxygen K edge. RIXS spectra of the hole-doped cuprates show clear…
Cooperative order in the weakly magnetic domain of LaFeAsOF near the doping phase boundary
M. Hiraishi, R. Kadono, M. Miyazaki +6
Spatial phase separation into mesoscopic domains of non-magnetic [superconducting (SC) below Tc = 25.5 K] and two kinds of magnetic phases, one showing disordered spin density wave…
Role of magnetic chirality in polarization flip upon commensurate-incommensurate magnetic phase transition in YMnO
S. Wakimoto, H. Kimura, Y. Sakamoto +4
We have performed simultaneous measurements of magnetic chirality by using polarized neutrons and electric polarization along the b-axis of single crystals of YMn(Mn…
Strong spin resonance on BaFe2(As0.65P0.35)2 with Tc = 30 K
M. Ishikado, Y. Nagai, K. Kodama +13
We performed inelastic neutron scattering on powder sample of the P-doped iron-based superconductor BaFe2(As0.65P0.35)2 with Tc = 30K, whose superconducting (SC) order parameter is…
Inelastic neutron scattering study on the resonance mode in an optimally doped superconductor LaFeAsOF
S. Shamoto, M. Ishikado, A. D. Christianson +5
An optimally doped iron-based superconductor LaFeAsOF with K has been studied by inelastic powder neutron scattering. The magnetic excitation at $Q=1.1…
Magnetic field effect on Fe-induced short-range magnetic correlation and electrical conductivity in BiPbSrCuFeO
S. Wakimoto, H. Hiraka, K. Kudo +8
We report electrical resistivity measurements and neutron diffraction studies under magnetic fields of BiPbSrCuFeO, in which ho…
Degradation of superconductivity and spin fluctuations by electron over-doping in LaFeAsOF
S. Wakimoto, K. Kodama, M. Ishikado +9
Low energy spin fluctuations are studied for the electron-doped Fe-based superconductor LaFeAsO(1-x)F(x) by inelastic neutron scattering up to the energy transfer of w = 15 meV usi…
Spin chirality and electric polarization in multiferroic compounds MnO (Ho, Er)
S. Wakimoto, H. Kimura, M. Fukunaga +5
Polarized neutron diffraction experiments have been performed on multiferroic materials MnO (Ho, Er) under electric fields in the ferroelectric commensurate (CM)…
Absence of time reversal symmetry breaking in La_{2-x}Sr_{x}CuO_{4}
G. J. MacDougall, A. A. Aczel, J. P. Carlo +6
We have performed zero-field muon spin rotation measurements on single crystals of La_{2-x}Sr_{x}CuO_{4} to search for spontaneous currents in the pseudo-gap state. By comparing me…
