Effect of Oxygen Saturation on AFM-WFM-HTSC Transition Temperatures in RuSr2(Eu1.5Ce0.5)Cu2O10-δ Ceramic Samples

E. Yu. Beliayev, I. G. Mirzoev

英文摘要:

The effect of annealing in high pressure oxygen atmosphere on superconducting transition temperatures for ceramic samples of magnetic superconductor europium based 1222 ruthenocuprate was studied. It was shown that the properties of the samples are consistent with the behavior of granular superconducting system. As a result of oxygen saturation the superconducting transition temperatures become higher. Particularly, the shift of superconducting transition temperature for the intergranular medium is 9.2 K and for the matter within the granules 6.8 K. This difference is supposed due to the mechanism of oxygen diffusion along the grain boundaries. In the temperature range between 135 K and 350 K the behavior of resistance obeyed the Mott law of variable range hopping for three dimensional case.
