Superconductivity on the verge of metal-insulator transition in Cu $_{1 - x}$ Zn $_{x}$ Ir $_{2}$ S $_{4}$ probed by $μ$ SR

K. M. Kojima, M. Miyazaki, M. Hiraishi +6

The thiospinel CuIr $_{2}$ S $_{4}$ undergoes a metal-insulator transition below $\approx$ 230 K, which is suppressed by substitution of Cu with Zn (Cu $_{1 - x}$ Zn $_{x}$ Ir $_{2}$ S $_{4}$ ) to induce…

Metal-Insulator Transition and Pseudogap in Bi $_{1.76}$ Pb $_{0.35}$ Sr $_{1.89}$ CuO $_{6 + δ}$ High- $T_{c}$ Cuprates

M. Miyazaki, R. Kadono, M. Hiraishi +6

It is inferred from bulk-sensitive muon Knight shift measurement for a Bi $_{1.76}$ Pb $_{0.35}$ Sr $_{1.89}$ CuO $_{6 + δ}$ single-layer cuprate that metal-insulator (MI) transition (in th…

Bulk superconductivity in undoped T'-La $_{1.9}$ Y $_{0.1}$ CuO $_{4}$ probed by muon spin rotation

K. M. Kojima, Y. Krockenberger, I. Yamauchi +8

The Meissner effect has been directly demonstrated by depth-resolved muon spin rotation measurements in high-quality thin films of the T'-structured cuprate, T'-La $_{1.9}$ Y $_{0.1}$ …

Magnetic frustration in iridium spinel compound CuIr $_{2}$ S $_{4}$

K. M. Kojima, 2 R. Kadono, M. Miyazaki +6

We demonstrate via a muon spin rotation experiment that the electronic ground state of the iridium spinel compound, CuIr $_{2}$ S $_{4}$ , is not the presumed spin-singlet state but a nove…

Cooperative order in the weakly magnetic domain of LaFeAsO $_{1 - x}$ F $_{x}$ near the doping phase boundary

M. Hiraishi, R. Kadono, M. Miyazaki +6

Spatial phase separation into mesoscopic domains of non-magnetic [superconducting (SC) below Tc = 25.5 K] and two kinds of magnetic phases, one showing disordered spin density wave…

Magnetic Phase Diagram of the Hole-doped Ca $_{2 - x}$ Na $_{x}$ CuO $_{2}$ Cl $_{2}$ Cuprate Superconductor

K. Ohishi, I. Yamada, A. Koda +6

We report on the magnetic phase diagram of a hole-doped cuprate Ca $_{2 - x}$ Na $_{x}$ CuO $_{2}$ Cl $_{2}$ , which is free from buckling of CuO $_{2}$ planes, determined by muon spin rotation…
