Sažetak
We report on ac susceptibility resistivity, thermopower and measurements of sintered magnetic superconductor RuSr2GdCu2O8. The antiferromagnetic phase transition at 133 K is seen clearly in the ac susceptibility as well as in the derivative of resistivity and thermopower. Above the antiferromagnetic transition, we have found some new evidences of the similarity between HTC compounds and the magnetic superconductor. The onset of superconductivity is observed by both transport methods at 46 K, and it is given an explanation why it is not seen in the ac susceptibility data. The end of the SC transition occurs at about 24 K in all measured properties. We discuss the steps broad SC transition, especially the maximum in susceptibility at 34 K, and compare our results with related studies reported in the literature.
