First-principles study of LaOPbBiS and its analogous compounds as thermoelectric materials
Keiya Kurematsu, Masayuki Ochi, Hidetomo Usui +1
LaOBiPbS is a kind of pnictogen-dichalcogenide layered compounds, which have recently been experimentally investigated as thermoelectric materials owing to their low thermal co…
Thermoelectric properties of (Ba,K)Cd2As2 crystallized in the CaAl2Si2-type structure
H. Kunioka, K. Kihou, H. Nishiate +4
As-Based Zintl compounds Ba1-xKxCd2As2 crystallized in the CaAl2Si2-type structure (space group P3-m1) were prepared using solid-state reactions followed by hot-pressing. We have s…
Multiple Antiferromagnetic Spin Fluctuations and Novel Evolution of Tc in Iron-based superconductors LaFe(As1-xPx)(O1-yFy) revealed by 31P-NMR Studies
T. Shiota, H. Mukuda, M. Uekubo +8
We report on 31P-NMR studies of LaFe(As_{1-x}P_x)(O_{1-y}F_{y}) over wide compositions for 0<x<1 and 0<y<0.14, which provide clear evidence that antiferromagnetic spin fluctuations…
Fermi-surface topological phase transition and horizontal order-parameter nodes in CaFeAs under pressure
R. S. Gonnelli, D. Daghero, M. Tortello +8
Iron-based compounds (IBS) display a surprising variety of superconducting properties that seems to arise from the strong sensitivity of these systems to tiny details of the lattic…
Enhancement of the NaCoO thermopower due to electronic correlations
P. Wissgott, A. Toschi, H. Usui +2
Using the merger of local density approximation and dynamical mean field theory, we show how electronic correlations increase the thermopower of NaCoO by 200%. The newl…
Incommensurate spin fluctuations in hole-overdoped superconductor KFe2As2
C. H. Lee, K. Kihou, H. Kawano-Furukawa +9
A neutron scattering study of heavily hole-overdoped superconducting KFeAs revealed a well-defined low-energy incommensurate spin fluctuation at [),0] with =…
