Abstract
We report the results of muon spin rotation and relaxation (μSR) measurements on the recently discovered layered Cu-based superconducting material La2(Cu1−xNix)5As3O2 (x=0.40 and 0.45). Transverse-field μSR experiments on both samples show that the temperature dependence of superfluid density is best described by a two-band model. The absolute values of zero-temperature magnetic penetration depth λab(0) were found to be 427(1.7) and 422(1.5) nm for x=0.40 and 0.45, respectively. Both compounds are located between the unconventional and the standard BCS superconductors in the Uemura plot. No evidence of time-reversal symmetry breaking in the superconducting state is suggested by zero-field μSR measurements.
