Abstract

We have investigated the magnetism and the superconductivity of the electron-doped Pr_1-xLaCe_xCuO₄ by means of zero-field muon spin rotation/relaxation and magnetic susceptibility measurements. At low temperatures, a well-defined muon spin rotation free from the effect of rare-earth moments was observed for samples with x≤0.08 corresponding to the antiferromagnetic (AF) order of Cu spins. Bulk superconductivity was identified in a wide Ce concentration range of 0.09≤x≤0.20 with a maximum transition temperature of 26 K. Abrupt appearance of the superconducting (SC) phase at x∼0.09 is concomitant with a destroy of the AF ordered phase, indicating the competitive relation between two phases. Possible relation between the wide SC phase and the lattice spacing is discussed.
