Oxygen-isotope effect on the in-plane penetration depth in underdoped Y_{1-x}Pr_xBa_2Cu_3O_{7-delta} as revealed by muon-spin rotation
R. Khasanov, A. Shengelaya, K. Conder +3
The oxygen-isotope (^16O/^18O) effect (OIE) on the in-plane penetration depth in underdoped Y_{1-x}Pr_xBa_2Cu_3O_{7-delta} was studied by muon-spin rotation. A pronoun…
Oxygen Isotope Effect of the Plane-Copper NQR Frequency in YBa_2Cu_4O_8
M. Mali, J. Roos, H. Keller +2
We report on high-precision measurements of the temperature dependence of the plane-^63Cu NQR line frequency nu_Q(Cu2) and the linewidth in normal and superconducting ^16O and ^18O…
^25Mg NMR study of the MgB_2 superconductor
M. Mali, J. Roos, A. Shengelaya +2
^25Mg NMR spectra and nuclear spin-lattice relaxation time, T_1, have been measured in polycrystalline ^25MgB_2 with a superconducting transition temperature T_c = 39.0 K in zero m…
Oxygen isotope effect on the in-plane penetration depth in underdoped La_{2-x}Sr_{x}CuO_{4} single crystals
J. Hofer, K. Conder, T. Sasagawa +4
We report measurements of the oxygen isotope effect (OIE) on the in-plane penetration depth λ_{ab}(0) in underdoped La_{2-x}Sr_{x}CuO_{4} single crystals. A highly sensitive magnet…
