$^{139}$La-NMR study of spin-dynamics coupled with hole mobility in $T$*-type La$_{0.86}$Eu$_{0.86}$Sr$_{0.28}$CuO$_{4-\delta}$

Autor: Takanori Taniguchi, Shunsaku Kitagawa, Kenji Ishida, Shun Asano, Kota Kudo, Motofumi Takahama, Peiao Xie, Takashi Noji, Masaki Fujita

In $T$*-type cuprate oxides with five oxygen coordination, little is known about the relationship between the spin correlations and dope carriers. We performed $^{139}$La-nuclear magnetic resonance (NMR) and electrical resistivity measurements on an

Publikováno v: Physical Review Materials. 5

We report a Cu $K$- and ${L}_{3}$-edge resonant inelastic x-ray scattering study of charge and spin excitations of bulk ${\mathrm{Nd}}_{2\ensuremath{-}x}{\mathrm{Ce}}_{x}{\mathrm{CuO}}_{4}$, with a focus on post-growth annealing effects. For the pare

Magnetic behavior of T′ -type Eu2CuO4 revealed by muon spin rotation and relaxation measurements

Autor: Shun Asano, H. Okabe, Koji Suzuki, Masaki Fujita, Akihiro Koda, Ryosuke Kadono, Isao Watanabe

Publikováno v: Physical Review B. 102

We performed muon-spin-rotation/-relaxation measurements to investigate the magnetic behavior of ${T}^{\ensuremath{'}}$-type ${\mathrm{Eu}}_{2}{\mathrm{CuO}}_{4}$ (ECO), which is the parent compound of electron-doped cuprate superconductors, and the

Revisiting the phase diagram of T*-type La$_{1-x/2}$Eu$_{1-x/2}$Sr$_x$CuO$_4$ using Oxygen $K$-edge X-ray absorption spectroscopy

Autor: Kenji Ishii, Yoshihisa Harada, Jun Miyawaki, Kohei Yamagami, Masaki Fujita, Shun Asano

Oxygen $K$-edge X-ray absorption spectroscopy measurements were conducted on T*-type La$_{1-x/2}$Eu$_{1-x/2}$Sr$_x$CuO$_4$ (LESCO) to estimate the hole density ($n_{\rm h}$) and investigate the oxidation annealing effect on $n_{\rm h}$. A drastic inc

Observation of two types of charge density wave orders in superconducting La$_{2-x}$Sr$_x$CuO$_4$

Autor: Katsuhiko Suzuki, Masaki Fujita, Steven A. Kivelson, Jiajia Wen, Sang Jun Lee, Shun Asano, Y. S. Lee, Hai Huang, Jason Knight, Jun-Sik Lee, Hoyoung Jang, Chi-Chang Kao

Publikováno v: Nature Communications, Vol 10, Iss 1, Pp 1-6 (2019)

The discovery of charge- and spin-density-wave (CDW/SDW) orders in superconducting cuprates has altered our perspective on the nature of high-temperature superconductivity (SC). However, it has proven difficult to fully elucidate the relationship bet
