dc.description.abstractCurrent-voltage (I-V) characteristics of MgB2 bulk sintered superconductor, prepared from the commercially available powder (Alfa-Aesar), have been investigated before and after several gamma irradiations up to 5000 MR. A minor increase in the normal state resistance of the sample was observed up to 5000 MR without any change in its critical temperature (T (c) ). I-V characteristics before and after gamma irradiation with different doses up to 5000 MR were shown and fitted to the expression VaeI (beta(T,B)) where beta approaches unity near T (c) before and after gamma irradiation. A decrease in the critical currents (I (c) ) with gamma irradiation up to 1000 MR was observed; after which they start to increase with higher irradiations up to 5000 MR without exceeding the critical currents before irradiation.en_US
