Abstract

The magnetic ground state of an electron-doped cuprate superconductor, Pr _1-xLaCe _xCuO _4+α-δ (x = 0.11, α ≃ 0.04), has been studied by means of muon spin rotation/relaxation (μSR) over a wide variety of oxygen depletion, 0.03 ≤ δ ≤ 0.12. The appearance of a weak random magnetism over the entire crystal volume has been revealed by a slow exponential relaxation. The absence of δ-dependence for random magnetism and a multiplet pattern of the muon Knight shift at higher fields strongly suggest that the random moments are associated with excited Pr ³⁺ ions under a crystal electric field.
