Doping dependence of the spatially modulated dynamical spin correlations and the superconducting-transition temperature in La 2-x Sr x CuO 4

Kohta Yamada, +13 more
- 01 Mar 1998 - 
TL;DR: In this article, a low-energy spin-fluctuation peak position shifts from ($\frac{1}{2}$ to ($ \frac{ 1}{2$\ifmmode\pm\else\textpm\fi{ \ensuremath{\delta}=x$, and the peak momentum width of the spin fluctuations at low energies is small throughout the superconducting concentration region.
Journal ArticleDOI

Neutron-scattering study of spin-density wave order in the superconducting state of excess-oxygen-doped La 2 CuO 4+y

Young S. Lee, +8 more
- 01 Aug 1999 - 
TL;DR: In this article, the spin-density wave order of a single crystal of a stage-4 superconducting state with a high temperature of 42 K was investigated and it was shown that the spin direction in the copper-oxide plane is similar to that in the undoped antiferromagnetic insulator.
Journal ArticleDOI

Direct Observation of a Magnetic Gap in Superconducting La 1.85 Sr 0.15 CuO 4 ( T c = 37.3 K )

Kohta Yamada, +8 more
- 21 Aug 1995 - 
TL;DR: The temperature dependence of the low energy incommensurate peak intensity at $(\ensuremath{-}y}^{2}), and the intensity below 3.5 meV dramatically decreases as the temperature decreases below ${T}_{c}$, vanishing into the background below $\ensureMath{\sim}15$ K.
Journal ArticleDOI

Systematic study of short-range antiferromagnetic order and the spin-glass state in lightly doped La 2 − x Sr x CuO 4

S. Wakimoto, +3 more
- 01 Aug 2000 - 
TL;DR: In this paper, a revised magnetic phase diagram in the lightly doped region of a cluster spin-glass was proposed, and the Curie constants calculated from the in-plane susceptibility are independent of the Sr concentration.
Journal ArticleDOI

An Overall Energy Spectrum of Magnetic Fluctuations in the Superconducting La1.85Sr0.15CuO4

Kazuyoshi Yamada, +8 more
- 15 Aug 1995 - 
TL;DR: In this article, high-energy pulsed neutron inelastic scattering experiments have been performed using single crystals of La 1.85 Sr 0.15 CuO 4 to study magnetic fluctuations in the superconducting phase.
