M. Ciszek et al., INFLUENCE OF HYDROGENATION ON INTERGRANULAR AND INTRAGRANULAR CRITICAL CURRENTS IN YBA2CU3O7-DELTA, Journal of applied physics, 76(4), 1994, pp. 2357-2360
The influence of hydrogenation on the inter- and intragranular critica
l current density has been studied using an ac technique. With increas
ing hydrogen content, intergranular critical current density decreases
drastically, whereas pinning inside the grains is increased.
