However, further comparison revealed that the slow cooled samples have improved superconductivity indicating higher 2223 phase formation compared to the air quenched samples for 0.08
This paper reports the preparation method of ErBa2Cu3O7- - Ag composites with Ag content of 5 wt% - 25 wt% silver. Resistance measurement was done using the four-point probe method in the temperature range of 79 K to 300 K. We found that the addition of silver decreases the normal state resistivity of the composite significantly with increasing Ag content. At 5% wt of silver, Tc increases from 88 K (pure sample) to 91 K. However Tczero remained approximately constant at 91 K for further addition of 10, 15 and 20 wt. % of silver. At 25 wt. % silver content, Tc value drops drastically to 68.5 K. The paper reports on the preparation methods of the composite material and the results of the resistance measurement. These results offer the possibility of using this composite material for the manufacture of superconducting wires. [Authors' abstract].
