Abstract

Grain boundaries (GBs) as two-dimensional defects strongly influence and determine the current carrying capabilities of superconductors, may it be by providing efficient pinning centres or by constituting weak links. In this chapter, GB issues of polycrystalline bulks and wires as well as polycrystalline and bicrystal thin films of Fe-based superconductors are discussed for the most-studied, application-relevant systems: LnFeAs(O,F) (Ln: lanthanoid), P-, Co-, and Ni-containing AeFe₂As₂, (Ae: alkali earth), and Fe(Se,Te) in comparison to the cuprate high-T _c superconductors.

previous chapter Future Potential of New High T c Iron-Based Superconductors

next chapter Control of the Critical Current Density Through Microstructural Design by Ho2O3 and Te Co-addition into MgB2 Processed by Ex Situ Spark Plasma Sintering

Due to the complex microstructure of these samples with different kinds of stacking faults and intergrowths, the magnetically measured self-field J _c values differ for B||c and B⊥c.
