    Field percolation and high current density in 80/20 DyBa2Cu3O7 − x/Dy2BaCuO5 bulk magnetically textured composite ceramics

    We measured the AC susceptibility of magnetically textured (123) 80%/211(20%) DyBaCuO composite in a special set-up in order to enhance the intergrain contribution. The synthesis process led to very clean “wea...

    Non-isovalent alkali metal “substitution” in YBa2Cu3O7−y granular ceramics

    The aim of this paper is to study the influence of non-isovalent “do**” in YBa2Cu3O7−y in particular on its synthesis conditions and on the resistive properties both with and without a magnetic field. We conce...

    Dimensionality crossover regimes due to microcrystalline anisotropy in the resistivity of granular Y1Ba2Cu3O7−y in weak magnetic fields at low temperature

    Precise measurements of the electrical resitivity of Y1Ba2Cu3O7−y have been taken in the temperature range between the “percolation transition” temperatureT R and the “superco...
