"Critical current anisotropy in nanostructured HLPE coated conductors";
Journal of Physics: Conference Series,
Coated conductors can be produced by hybrid liquid phase epitaxy (HLPE) with high growth rates and excellent critical current densities. Samples with a thickness of about 1 μm carrying a current of several 100 A/cm-width were reproducibly fabricated in this way.
In this paper we report on the critical current densities in HLPE coated conductors focussing on the angular dependence of Jc(H,θ). Of particular interest for future technical applications is a reduction of the ratio Jc(H||ab)/Jc(H||c). This can be achieved by defects induced during crystal growth and correlating with the c-axis of the conductor, which therefore predominately contribute to Jc(H||c). The correlation of the pinning sites will be discussed in terms of the Jc-anisotropy in fields of up to 6 T.
