Abstract
Stable and reproducible superconducting transition between 92 K and 10 0 K has been observed both resistively and magnetically in potassium d oped GdBa2Cu3O7-delta ceramic material. It has been found that the sin tering temperature as well as stoichiometry plays an important role in determining the value of T(c). Subtle changes in T(c) occur for certa in weight % of K. The effect of changing composition on the supercondu cting transition temperature is also reported here.
