Abstract

The influences of microstructure, connectivity, and disorder on the critical current density, (Formula presented.), are discussed to clarify the different mechanisms of (Formula presented.) in different magnetic field ranges for in situ and combined in situ/ex situ (Formula presented.) wires with nano SiC and malic acid codoping. Sintering temperature plays a very important role in the electromagnetic properties at different temperatures and under various magnetic fields. Connectivity, upper critical field, (Formula presented.), and irreversibility field, (Formula presented.), are studied to demonstrate the mechanism of (Formula presented.) dependence on magnetic field. The combined in situ/ex situ process is proved to be a promising technique for fabrication of practical (Formula presented.) wires.
