Strengthening Superconductivity in Macro-Arrays of Nanoclusters and Nanostructures

Abstract

Objective of this project was to create nanostructured superconducting systems with higher Hc and Jc for power applications as nanocomposite wires and also to search for new types of superconducting nanomaterials with higher critical temperature Tc. The interfacial novel phase have been confirmed to have a record Tc = 47-49 in Pr and other rare earth doped Ca 122 pnictide superconductors by ultrasensitive low-field microwave absorption method. Coexistence of lower Tc and higher Tc observed by LFMA proves the interfacial nature of newly found SC phase. on the contrary the LFMA in 122 pnictide shows only one signal and one phase. In thin films of FeSeTe films deposited by pulsed laser deposition very high Hc, (estimated to be 186 T by HWW formula) has been achieved at the compositions close to antiferomagnetic order. Flexible, weavable and knottable superconducting magnesium diboride yarns have been fabricated that provide attractive gravimetric properties as a superconductor, while having a 20 times lower density than for bulk MgB2.
