The conductivities of the perovskite layered compounds \(\mathrm{KLaNb}_{12} \mathrm{O}_{7}\) and its ion-exchanged forms \(M \mathrm{LaNb}_{2} \mathrm{O}_{7} \cdot x \mathrm{H}_{2} \mathrm{O}(M=\mathrm{Na} \cdot \mathrm{H})\) were investigated in the temperature range 20 to \(80^{\circ} \mathrm{C}\
Single-phase samples of \(\mathrm{La}_{3} \mathrm{Ni}_{2} \mathrm{O}_{7-\delta}\) with \(\delta=0,0.08\), and 0.65 were prepared and characterized by powder \(\mathrm{X}\)-ray diffraction, TGA, electrical resistivity, and magnetic susceptibility. The crystal symmetry of the as-prepared \((\delta=0.0
