Interplay between nuclear shell evolution and shape deformation revealed by magnetic moment of 75Cu
Y. Ichikawa, H. Nishibata, Y. Tsunoda +41
Exotic nuclei are characterized by a number of neutrons (or protons) in excess relative to stable nuclei. Their shell structure, which represents single-particle motion in a nucleu…
Emergent units of itinerant spin-state excitations in LaCoO
K. Tomiyasu, T. Nomura, Y. Kobayashi +3
Spin crossover is expected to enrich unusual physical states in various types of condensed matter. Through inelastic neutron scattering, we study the spin-state excitations in the…
Spin Nutation Induced by Atomic Motion in a Magnetic Lattice
Y. Kobayashi, Y. Shiraishi, A. Hatakeyama
An atom moving in a spatially periodic field experiences a temporary periodic perturbation and undergoes a resonance transition between atomic internal states when the transition f…
NMR Studies on the Superconducting Symmetry of Iron Pnictide Systems
Y. Kobayashi, A. Kawabata, S. C. Lee +2
NMR longitudinal relaxation rates 1/T1 and Knight shifts K have been measured for superconducting samples of LaFe1-yCoyAsO1-xFx with y=0.0 and 0.0075 and for a nonsuperconducting m…
Element-Specific Phonon Density of States of Iron in LaFeAsO_{1-x}F_{x} and La_{1-x}Ca_{x}FePO
S. Higashitaniguchi, M. Seto, S. Kitao +8
We have measured element-specific Fe-phonon densities of states (Fe-PDOS) of LaFeAsO_{1-x}F_{x} (x = 0, 0.11) and La_{1-x}Ca_{x}FePO (x = 0.13) by using nuclear resonant inelastic…
Spin Ordering in LaOFeAs and Its Suppression in Superconductor LaO0.89F0.11FeAs Probed by Mössbauer Spectroscopy
S. Kitao, Y. Kobayashi, S. Higashitaniguchi +6
The 57Fe Mössbauer spectroscopy was applied to an iron-based layered superconductor LaO0.89F0.11FeAs with a transition temperature of 26 K and its parent material LaOFeAs. Througho…
