The first muSR measurement of magnetism in the T*214 cuprate

Abstract: We propose the first muSR measurements on T*-structured La0.9+x/2Eu0.9+x/2Sr0.2-xCuO4 to investigate the effect of hole-doping and the oxygen annealing on the magnetism. Since the existence of strong AF correlation in the SC phase is suggested by ARPES, the magnetic correlation evolves in a different way from that in hole-doped T-La2-xSrxCuO4. Furthermore, the superconducting phase emerges after the oxygen annealing, which is opposite manner to the reduction annealing in the case of electron doped T'-Nd2-xCexCuO4.Therefore, T*-system provide a opportunity to extract a fundamental role of magnetism for the emergence of superconducting phase from a comparison with results for T-La2-xSrxCuO4 and T'-Nd2-xCexCuO4.We will draw AF ordered and SC phase diagrams for as-grown and oxygen annealed samples, and get information on the macroscopic coexistence of AF and SC phases.
