The dependence of critical current density on the magnetic field strength and orientation, J(B,theta), is the major obstacle to high-field applications of superconductors. This project therefore aims at the development of graded-pinning YBa2Cu3Oy superconducting thin films. The aim is to grow nanoparticles in specific directions along the YBCO films and the combination of layers with different additions and different pinning orientations will be grown by layer over layer deposition with ink jet printing.
