Abstract:

In an effort to integrate superconducting, conducting, ferrite and insulating thin films to produce microwave devices such as phase shifters and circulators, thin films single and bi-layer of ferrites Strontium Hexaferrite, Fe3O4, superconductors YBa2Cu3O7-x, buffer layers MgO, and ground planes SrRuO3, CaRuO3 were grown by the technique of laser ablation on semiconducting Si, GaAs, ferrite YIG, and insulating LaAlO3 substrates. All films grown were epitaxial as shown by 4 circle x-ray diffractometry. The magnetic properties of the films were characterized by magnetometry and by FMR. 4 wire resistance measurements were used to characterize the superconducting properties.
