Inelastic neutron-scattering measurements of a three-dimensional spin resonance in the FeAs-based BaFe1.9Ni0.1As2 superconductor.
We use inelastic neutron scattering to study magnetic excitations of the FeAs-based superconductor BaFe1.9Ni0.1As2 above and below its T_{c} (=20 K). In addition to gradually open a spin gap at the in-plane antiferromagnetic ordering wave vector (1, 0, 0), the effect of superconductivity is to form a three-dimensional resonance with clear dispersion along the c axis. The intensity of the resona...
متن کاملQuantum dynamics of a hydrogen molecule inside an anisotropic open-cage fullerene: coupled translation-rotation eigenstates and comparison with inelastic neutron scattering spectroscopy.
We report rigorous quantum five-dimensional (5D) calculations of the translation-rotation (T-R) energy levels and wave functions of H(2) inside aza-thia-open-cage fullerene (ATOCF). Translational and rotational excitations of this endohedral complex have been measured in a recent inelastic neutron scattering (INS) study, enabling direct comparison between theory and experiment. ATOCF has no sym...
متن کاملInelastic Neutron Scattering Studies of the Spin and Lattice Dynamics in Iron Arsenide Compounds
Although neutrons do not couple directly to the superconducting order parameter, they have nevertheless played an important role in advancing our understanding of the pairing mechanism and the symmetry of the superconducting energy gap in the iron arsenide compounds. Measurements of the spin and lattice dynamics have been performed on non-superconducting ‘parent’ compounds based on the LaFeAsO ...
متن کاملTheoretical Analysis of Inelastic Neutron Scattering in Solid Hydrogen
The inelastic-neutron-scattering cross section of ( J=1) solid hydrogen is studied and the experimental data of Stein and co-workers analyzed. The rms displacement ⟨u2⟩1/2 is deduced from the data via different methods and mutually consistent values of order 0.65 Å are obtained. The enhancement of the cross section at the libron energy due to libron-phonon interactions is found to be the same, ...
متن کاملInelastic neutron scattering of hydrogen trapped in solid argon
2014 Molecular hydrogen was isolated in an argon matrix. Its inelastic neutron scattering functions at momentum transfers of 1 to 7 Å-1 were compared with those of solid hydrogen. Both samples show free rotation without line shift. At high momentum transfer (7 Å-1), the spectrum of pure hydrogen is affected by recoil, whereas no recoil effects could be seen in matrix isolated H,. Revue Phys. Ap...
