Superconductivity on the verge of metal-insulator transition in Cu $_{1 - x}$ Zn $_{x}$ Ir $_{2}$ S $_{4}$ probed by $I^¼$ 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…

Molecular dynamics of $c i s$ -polybutadiene across the glass transition revealed by muonated-radical spin relaxation

S. Takeshita, H. Okabe, M. Hiraishi +7

The local molecular motion of $c i s$ -polybutadiene, a typical polymeric material exhibiting a glass transition ( $T_{g} = 168$ K), is investigated by the spin relaxation of muonate…

Correlation between ferroelectricity and torsional motion of acetyl groups in tris(4-acetylphenyl)amine observed by muon spin relaxation

J. G. Nakamura, M. Hiraishi, H. Okabe +4

It is demonstrated by muon spin relaxation and resonance experiments that the switchable spontaneous polarization of the organic ferroelectric compound tris(4-acetylphenyl)amine (T…

Slow polymer dynamics in poly(3-hexylthiophene) probed by muon spin relaxation

S. Takeshita, K. Hori, M. Hiraishi +5

The molecular dynamics of regioregulated poly(3-hexylthiophene) P3HT is investigated using muon spin relaxation ( $I^¼$ SR). The response of the $I^¼$ SR spectra to a longitudinal magne…
