| Popis: | The compound ${\mathrm{LaCuO}}_{3}$, and the substituted series ${\mathrm{La}}_{1\mathrm{\ensuremath{-}}\mathrm{x}}$${\mathrm{M}}_{\mathrm{x}}$${\mathrm{CuO}}_{3}$, where M=Mg, Ca, Sr, Ba, Pb, Sc, Y, Pr, Nd, Sb, Bi, Ti, Zr, or Ce and ${\mathrm{LaCu}}_{1\mathrm{\ensuremath{-}}\mathrm{x}}$${\mathrm{M}}_{\mathrm{x}}^{\ensuremath{'}}$${\mathrm{O}}_{3}$, where M\ensuremath{'}=Cr, Fe, Ni, Zn, or Ag, have been prepared by high-pressure, high-temperature synthesis. The electrical resistivity was checked qualitatively, and the magnetic susceptibility measured to minimum temperatures of 2\char21{}50 K. No evidence of the Meissner effect was found in any of the compositions studied, indicative of the absence of superconductivity in at least 99% of the sample volume. |
