Critical current density and microstructure of YBa2Cu4O8

We investigated the intragranular critical current density Jc in YBa2Cu4O8 prepared by two routes with different oxygen pressures at various temperatures and applied fields. A relationship between the Jc’s and the microstructures observed by transmission electron microscopy is discussed. The magnitu...
