Abstract
HoBa2Cu3O7-δ (HBCO) thin films were grown by reactive sputtering on SrTiO3 (STO), (LaAlO3)0.3(Sr2 TaAlO6)0.7 (LSAT), and NdGaO3 (NGO) substrates for optimization of electrical properties for superconductive electronics. By changing deposition temperature and oxygen partial pressures we were able to obtain films with critical temperatures of 92 K and critical current density of 3 MA/cm2. HBCO Josephson junctions were fabricated using focused helium ion beam irradiation that exhibited excellent properties.
