Abstract
Superconducting ferromagnet Ru1-xSr2Gd Cu2+xO8 with x=0, 0.2 and 0.4 has been synthesized and characterized structurally, microstructurally and electrically by x-ray diffraction, scanning electron microscopy and resistivity measurements. Arrhenius plots of ln(ρ/ρo) vs T and potential energy are being reported. Two-different regimens of pinning are found. We show that U0 data can be interpreted in terms of a possible structural change in the grain boundaries.
