Microscopic Evidence of Direct Coupling between Magnetic and Superconducting Order Parameters in BaFe $_{2}$ (As $_{1 - x}$ P $_{x}$ ) $_{2}$

T. Iye, Y. Nakai, S. Kitagawa +5

The coexistence of magnetism and superconductivity in the isovalent-P-substituted BaFe $_{2}$ (As $_{1 - x}$ P $_{x}$ ) $_{2}$ has been investigated microscopically by $^{31}$ P-NMR measurements.…

Metamagnetic Behavior and Kondo Breakdown in Heavy-Fermion CeFePO

S. Kitagawa, H. Ikeda, Y. Nakai +5

We report that nonmagnetic heavy-fermion (HF) iron oxypnictide CeFePO with two-dimensional XY-type anisotropy shows a metamagnetic behavior at the metamagnetic field H_M \simeq 4 T…

Non-magnetic pair-breaking effect on La(Fe_{1-x}Zn_{x})AsO_{0.85} studied by NMR and NQR

S. Kitagawa, Y. Nakai, T. Iye +5

$^{75}$ As and $^{139}$ La NMR and nuclear quadrupole resonance (NQR) studies on Zn-substituted LaFeAsO $_{0.85}$ have been performed to investigate the Zn-impurity effects microscopi…
