Superconducting transition temperatures in the electronic and magnetic phase diagrams of Sr2VFeAsO3-delta, a superconductor
Yujiro Tojo, Taizo Shibuya, Tetsuro Nakamura +13
We elucidate the magnetic phases and superconducting transition temperatures (Tc) in Sr2VFeAsO3-delta (21113V), an iron-based superconductor with a thick-blocking layer fabricated…
Ferromagnetic Quantum Critical Point Induced by Tuning the Magnetic Dimensionality of the Heavy-Fermion Iron Oxypnictide Ce(RuFe)PO
Shunsaku Kitagawa, Kenji Ishida, Tetsuro Nakamura +2
We have performed 31P-NMR measurements of the c-axis-aligned poly-crystal Ce(Ru1-xFex)PO with a two-dimensional layered structure in order to understand the origin of TCurie suppre…
Paramagnetic Phase of a Heavy-Fermion Compound, CeFePO, Probed by 57Fe Mössbauer Spectroscopy
Tetsuro Nakamura, Takashi Yamamoto, Masanori Matoba +2
57Fe Mössbauer spectroscopy was applied to an iron-based layered compound CeFePO. At temperatures from 9.4 to 293 K, no magnetic splitting was observed in the Mössbauer spectra of…
Full Self-Consistent Projection Operator Approach to Nonlocal Excitations in Solids
Yoshiro Kakehashi, Tetsuro Nakamura, Peter Fulde
A self-consistent projection operator method for single-particle excitations is developed. It describes the nonlocal correlations on the basis of a projection technique to the reta…
First-principles dynamical CPA to finite-temperature magnetism of transition metals
Y. Kakehashi, T. Tamashiro, M. A. R. Patoary +1
We present here the first-principles dynamical CPA (coherent potential approximation) combined with the tight-binding LMTO LDA+U method towards quantitative calculations of the ele…
Non local theory of excitations applied to the Hubbard model
Y. Kakehashi, T. Nakamura, P. Fulde
We propose a nonlocal theory of single-particle excitations. It is based on an off-diagonal effective medium and the projection operator method for treating the retarded Green func…
