Electron Localization in La_{2-x}Sr_xCuO_4 and the Role of Stripes
Seiki Komiya, Yoichi Ando
The normal-state in-plane resistivity (ρ_{ab}) is measured in lightly Zn-doped La_{2-x}Sr_xCuO_4 (LSCO) crystals with 0.06 \leq x \leq 0.17 to systematically study the localization…
Spin reorientation and in-plane magnetoresistance of lightly doped La_{2-x}Sr_{x}CuO_{4} in magnetic fields up to 55 T
S. Ono, Seiki Komiya, A. N. Lavrov +4
The magnetoresistance (MR) in the in-plane resistivity is measured in magnetic fields up to 55 T in lightly doped La_{2-x}Sr_{x}CuO_{4} in the Néel state (x = 0.01) and in the spin…
Magic Doping Fractions in High-Temperature Superconductors
Seiki Komiya, Han-Dong Chen, Shou-Cheng Zhang +1
We report hole-doping dependence of the in-plane resistivity ρ_{ab} in a cuprate superconductor La_{2-x}Sr_{x}CuO_{4}, carefully examined using a series of high-quality single crys…
Magnetic order in lightly doped La_{2-x}Sr_{x}CuO_{4}
A. Gozar, B. S. Dennis, G. Blumberg +2
We study long wavelength magnetic excitations in lightly doped La_{2-x}Sr_{x}CuO_{4} (x < 0.03) detwinned crystals. The lowest energy magnetic anisotropy induced gap can be underst…
Molecular orbital excitations in cuprates
Young-June Kim, J. P. Hill, G. D. Gu +10
We report resonant inelastic x-ray scattering studies of electronic excitations in a wide variety of cuprate compounds. Specifically, we focus on the charge-transfer type excitatio…
Electronic specific heat and low energy quasiparticle excitations in superconducting state of single crystals
Hai-Hu Wen, Zhi-Yong Liu, Fang Zhou +6
Low temperature specific heat has been measured and extensively analyzed on a series of single crystals from underdoped to overdoped regime. From these data the…
