    Deposition temperature is an important parameter to control in pulsed laser deposition of thin films, as it affects the ad-atom mobility and diffusion in regards to film growth. Increased growth temperature can also result in increased stacking fault densities in YBa2Cu3O7- (YBCO) films. This research investigates the influence of deposition temperature on the critical current density, critical temperature, and the microstructure of YBCO thin films double doped with BaHfO3 and Y2O3. A KrF excimer laser was used to produce thin films of YBCO doped with 4 vol.% BaHfO3 and 3 vol. % Y2O3 on LaAlO3 (LAO) substrates at various deposition temperatures from 790 - 825. The growth temperature influence on the flux pinning landscape and Jc (H,T,) properties (T = 5 - 77K, H = 0 - 9T, = 0 -180) of these films will be presented.
