Abstrakt: Presents a study that investigated the relationship between weak ferromagnetism, superconductivity, and lattice parameter in the A[sub2-x-y]B[subx]Ce[suby]CuO[sub4] (A,B...La, Pr, Nd, Sm, Eu, Gd, Y) compounds. Information on ac susceptibility as a function of temperature of Eu[sub1.8]Y[sub02]CuO[sub4]; Spectra for Sm[sub2-x]Y[subx]CuO[sub4] measured at 9Ghz and 263 Kelvin; Analysis of dc susceptibility measured at 10 Oe on a powder sample of La[sub1.1]Gd[0.75]Ce[sub0.15]CuO[sub4].
