The isovalent-substituted iron pnictide compound SrFe$_{2}$(As$_{1-x}$P$_{x}$)$_{2}$ exhibits multiple evidence for nodal superconductivity via various experimental probes, such as the penetration depth, nuclear magnetic resonance and specific heat m

Unusual nodal behaviors of the superconducting gap in the iron-based superconductor Ba(Fe$_{0.65}$Ru$_{0.35}$)$_2$As$_2$: Effects of spin-orbit coupling

Publikováno v: Phys. Rev. B 95, 104504 (2017)

We have investigated the superconducting gap of optimally doped Ba(Fe$_{0.65}$Ru$_{0.35}$)$_2$As$_2$ by angle-resolved photoemission spectroscopy (APRES) using bulk-sensitive 7 eV laser and synchrotron radiation. It was found that the gap is isotropi

Se content $x$ dependence of electron correlation strength in Fe$_{1+y}$Te$_{1-x}$Se$_{x}$

Autor: Ambolode II, L. C. C., Okazaki, K., Horio, M., Suzuki, H., Liu, L., Ideta, S., Yoshida, T., Mikami, T., Kakeshita, T., Uchida, S., Ono, K., Kumigashira, H., Hashimoto, M., Lu, D. -H., Shen, Z. -X., Fujimori, A.

The iron chalcogenide Fe$_{1+y}$Te$_{1-x}$Se$_{x}$ on the Te-rich side is known to exhibit the strongest electron correlations among the Fe-based superconductors, and is non-superconducting for $x$ < 0.1. In order to understand the origin of such beh

In-plane electronic anisotropy in the antiferromagnetic-orthorhombic phase of isovalent-substituted Ba(Fe$_{1-x}$Ru$_x$)$_2$As$_2$

Publikováno v: Phys. Rev. B 92, 094503 (2015)

We have studied the anisotropy in the in-plane resistivity and the electronic structure of isovalent Ru-substituted BaFe$_2$As$_2$ in the antiferromagnetic-orthorhombic phase using well-annealed crystals. The anisotropy in the residual resistivity co

Suppression of the antiferromagnetic pseudogap in the electron-doped high-temperature superconductor by 'protect annealing'

Publikováno v: Nat. Commun. 7:10567 (2016)

In the hole-doped cuprates, a small amount of carriers suppresses antiferromagnetism and induces superconductivity. In the electron-doped cuprates, on the other hand, superconductivity appears only in a narrow range of high electron concentration ($\

Strongly three-dimensional electronic structure and Fermi Surfaces of SrFe$_{2}$(As$_{0.65}$P$_{0.35}$)$_{2}$: Comparison with BaFe$_{2}$(As$_{1-x}$P$_{x}$)$_{2}$

Autor: Suzuki, H., Kobayashi, T., Miyasaka, S., Yoshida, T., Ambolode II, L. C. C., Ideta, S., Yi, M., Hashimoto, M., Lu, D. H., Shen, Z. -X., Ono, K., Kumigashira, H., Tajima, S., Fujimori, A.

Publikováno v: Physical Review B 89, 184513 (2014)

The isovalent-substituted iron-pnictide superconductor SrFe$_{2}$(As$_{1-x}$P$_{x}$)$_{2}$ ($x$=0.35) has a slightly higher optimum critical temperature than the similar system BaFe$_{2}$(As$_{1-x}$P$_{x}$)$_{2}$, and its parent compound SrFe$_{2}$As
