Abstract:
1. Process for the preparation of the layer architecture for a coated conductor comprising a seed layer and a further layer by metal organic deposition, said process comprising the following steps: coating onto a biaxialy textured metal substrate, a precursor solution via metal organic deposition (MOD), for the formation of a seed layer of general formula (Ce subjecting the freshly coated seed later to a heat treatment comprising heating to a first temperature for pyrolysis and heating to a second temperature for crystallization, wherein the pyrolysis is carried out under a first more oxidizing condition than a second oxidizing condition for the crystallization, wherein the first temperature for pyrolysis is lower than the second temperature for crystallization, and coating onto the seed layer a precursor solution for forming a further layer of general formula La subjecting the freshly coated further layer to a heat treatment wherein the heat treatment of the freshly coated further layer is carried out at a third less oxidizing condition than said first oxidizing condition of said pyrolysis step of the heat treatment of the freshly deposited seed layer.
