The addition of different insulating, non-reactive nano-phases to YBa2Cu3O7-x (YBCO) superconductor thin films improves current density by combining different flux pinning mechanisms. Additions of BaZrO3, BaSnO3, and BaHfO3 nano-rods has been shown to have positive effects on flux pinning and the resulting current densities attained. In particular, BaHfO3 is an attractive addition since it...
Utilizing insulating nano-phase materials, such as BaZrO3 (BZO) in YBa2Cu3O7-δ films has been shown to increase flux pinning and current density. However, the defective BZO nanorod interface, resulting from its lattice mismatch with YBCO, prevents obtaining optimum pinning force. This research explores the effect of Ca doped YBCO space layers in the multilayer composite film, on the BZO...
It is discovered heredity in physical properties in HTSC-thick films after processing HTSC-powders by method of the electromagnetic separation (EMS) . The method was developed for EMS HTSC-powdered superconductors suspended in liquid nitrogen in alternating magnetic field.[1] In the thick film deposition process HTSC is simply heated and "painted" on to the substrate and then fired in a...
