La-NMR study of spin-dynamics coupled with hole mobility in *-type LaEuSrCuO
Takanori Taniguchi, Shunsaku Kitagawa, Kenji Ishida +6
In *-type cuprate oxides with five oxygen coordination, little is known about the relationship between the spin correlations and dope carriers. We performed La-nuclear m…
Magnetism behavior of -type EuCuO revealed by muon spin rotation/relaxation measurements
M. Fujita, K. M. Suzuki, S. Asano +4
We performed muon spin rotation/relaxation measurements to investigate the magnetic behavior of -type EuCuO (ECO), which is the parent compound of electron-dope…
Fermi-liquid state in *-type LaEuSrCuO revealed via element substitution effects on magnetism
Takanori Taniguchi, Kota Kudo, Shun Asano +4
Despite its unique structural features, the magnetism of single-layered cuprate with five oxygen coordination (*-type structure) has not been investigated thus far. Here, we rep…
