We present zero-field muon spin relaxation ({mu}SR) measurements of La{sub 1.6{minus}x}Nd{sub 0.4}Sr{sub x}CuO{sub 4} with x=0.125,0.15,0.2;thinspLa{sub 1.475}Nd{sub 0.4}Ba{sub 0.125}CuO{sub 4},thinspLa{sub 1.875}Ba{sub 0.125}CuO{sub 4}, and La{sub 1.875}Ba{sub 0.125{minus}y}Sr{sub y}CuO{sub 4} with y=0.025,0.065. All of the samples with dopant concentrations x+y{le}0.15 show similar static magnetic order with coherent precession of the muon spins below T{sub N}{approx}30thinspK, with a T{r_arrow}0 ordered Cu moment {approx}0.3{mu}{sub B}. The samples with x=0.20 show no coherent precession but manifest two distinct relaxation regimes, typical of quasistatic magnetism. We then present transverse-field {mu}SR hysteresis measurements of the La{sub 1.45}Nd{sub 0.4}Sr{sub 0.15}CuO{sub 4} and La{sub 1.4}Nd{sub 0.4}Sr{sub 0.2}CuO{sub 4} systems that show a large superconducting response below approximately 7 K and 12 K, respectively. We argue that superconductivity and magnetic order coexist in the x=0.15 system. {copyright} {ital 1998} {ital The American Physical Society}
