Description
Electron spin-freezing at Tf=8 K has been detected in superconducting (Tc=12 K) single crystal La2CuO4+y (y ≅ 0.03) by ZF-μSR. According to diffraction data, the crystal is in Bmab phase without any traces of structural phase separation. TF-μSR experiment has shown that no Abrikosov flux line lattice is formed below Tc. The data allow us to assume that the magnetic and superconducting regions in the crystal are space separated on the microscopic scales ∼ 102 A. The presence of large field induced broadening of the Knight shift distribution kσ > 1000 ppm indicates that the crystal contains micro-regions possessing enhanced magnetic susceptibility
