The　growth　of　the　nanostructured　YBa(2)Cu(3)O(6+x)　(YBCO)　films　is　investigated　for　the　first　time　on　biaxially　textured　NiW　substrates　used　in　coated　conductor　technology.　The　optimization　process　of　superconducting　layers　is　made　in　wide　magnetic　field　and　temperature　range　in　order　to　understand　the　vortex　pinning　structure　and　mechanism　in　our　films　prepared　from　nanostructured　material.　Structural　analysis　shows　that　growth　mechanism　in　YBCO　films　grown　on　NiW　is　completely　different　when　compared　to　YBCO　on　STO.　Films　on　NiW　are　much　rougher,　there　is　huge　in-plane　variation　of　YBCO　crystals　and　moreover　out-of-plane　long　range　lattice　ordering　is　greatly　reduced.　Magnetic　measurements　demonstrate　that　j(c)　in　films　grown　on　NiW　is　higher　in　high　magnetic　fields　and　low　temperatures.　This　effect　is　connected　to　the　amount　of　pinning　centres　observed　in　films　on　metal　substrates　which　are　effective　at　low　temperature　range.　(C)　2010　Elsevier　B.V.　All　rights　reserved.
