Abstract
The striking influence of the growth kinetics and substrate enhanced surface mobility on thecontrol of the self-assembly of rare earth tantalate particles (1.5 mol% of nanoparticles inYBa2Cu3O7 thin films) is demonstrated. Strongly enhanced flux pinning, control of the anisotropyproperty and superior critical current densities were achieved. Owing to the unique abilityto probe nanoparticle self-assembly through determination of the nature andextent of the anisotropy of the superconducting properties, this system serves asthe perfect model system for understanding how to tune and control functionalnanocomposite nanostructures for a wide range of multifunctional applications.
