Journal ArticleDOI

TL;DR: It is found that control of the nontrivial orbital moment in the octahedral Fe sites through the Al substitution is crucial for fine-tuning the magnetic anisotropy and obtaining the conspicuously improved ME characteristics.
Journal ArticleDOI
Pauli-limiting effects in the upper critical fields of a clean LiFeAs single crystal
TL;DR: In this paper, the temperature dependence of the upper critical field in LiFeAs single crystal was investigated by direct measurements of resistivity under static magnetic fields up to 36 T, and it was shown that the Maki parameter of LiFeA has a lower temperature than the orbital limiting field.
Journal ArticleDOI

TL;DR: In this paper, an improved selection of the elastic events and reduced background contributions yielded a small systematic reduction in the ratio {mu}{sub p}G{sub E}/G {sub M} compared to the original analysis.
Journal ArticleDOI
Orbital selective Fermi surface shifts and mechanism of high T(c) superconductivity in correlated AFeAs (A=Li, Na).
Geunsik Lee,Hyo Seok Ji,Yeongkwan Kim,Changyoung Kim,Kristjan Haule,Gabriel Kotliar,Bumsung Lee,Seunghyun Khim,Kee Hoon Kim,Kwang S. Kim,Ki-Seok Kim,Ji Hoon Shim +11 more
TL;DR: It is shown that marginal breakdown of the FS nesting is an essential condition to the spin-fluctuation mediated superconductivity, while the good FS nesting in NaFeAs induces a spin density wave ground state.
Journal ArticleDOI
Longer-range lattice anisotropy strongly competing with spin-orbit interactions in pyrochlore iridates
Liviu Hozoi,Hlynur Gretarsson,J. P. Clancy,Byung Gu Jeon,Bumsung Lee,Kee Hoon Kim,V. Yushankhai,V. Yushankhai,Peter Fulde,Peter Fulde,Diego Casa,Thomas Gog,Jungho Kim,Ayman Said,Mary Upton,Young-June Kim,Jeroen van den Brink +16 more
TL;DR: In this paper, it was shown that the primary source for quenching the spin-orbit interaction is not a distortion of the IrO{}_{6}$ octahedra but longer-range lattice anisotropies which inevitably break the local cubic symmetry.
