Popis:	For applying tensile or compressive uniaxial strain to functional thin films, we propose a novel approach in combining a piezoelectric-based device and a technical metallic substrate used widely in the 2nd generation coated conductors (i.e. superconducting tapes). A strain-induced shift of the superconducting transition temperature of 0.1 K for Co-doped BaFe2As2 was observed along [100] direction, corresponding to a uniaxial pressure derivative dTc/dp100=-4 K/GPa. For Mn3CuN, a uniaxial strain derivative along [100] direction of the Curie temperature dTC/de100=13 K/% was observed. The current approach is applicable to various functional thin films in a wide range of temperatures. Comment: 5 figures
