Temperature dependence of (μ−O) paramagnetic shift in highTc superconductor La2−xSr x CuO4
Section III.5: High Tc Superconductivity
Abstract
In order to investigate the electronic structure around oxygen in superconducting La2−xSr x CuO4 (x=0.10 and 0.14), precise measurements were carried out on the paramagnetic Knight shifts in the spin rotation frequency of the negative muon bound to the oxygen with reference to antiferromagnetic La2−xSr x CuO4 (x=0.05). Remarkable temperature as well as crystalline-axis dependence was observed for the highTc case with a divergence character towardsTc. Possible mechanisms to explain the observed results are given.
