Characterisation of the sol–gel process in the superconducting NdBa2Cu3O7−y system†
Abstract
The objective of this paper is to obtain a better insight into the sol–gel mechanism of water-based precursors for the development of thin NdBa2Cu3O7−y (NBCO) superconducting films. The influence of metal complexation behaviour on the formation of transparent and homogenous gels after the combination of different metal salts and
