  1. Outline • Motivation (isolators) • Garnet Layer • Fabrication • Characterization • Buffer Layers • Permanent Magnets • Photonic Crystals

  2. Confining ring SmCo Target SiO2 substrate Ar SmCo : RF Sputtering • Demagnetized SmCo bar magnet on 8” Cu disk target • Use confining ring • Fused quartz substrates RF Sputter System

  3. XRD of Permanent Magnet Film Majority phase is Sm2Co17

  4. VSM of Permanent Magnet Film Ms: 1177emu/cm3 Mr: 1024emu/cm3 Hc: 465Oe Sm2Co17 SmCo5

  5. Outline • Motivation (isolators) • Garnet Layer • Fabrication • Characterization • Buffer Layers • Permanent Magnets • Photonic Crystals

  6. Line Defect Point Defect Magneto Photonic Crystal Hexagonal Photonic Crystal Array TE Band Gap

  7. Photonic Crystal Design Band Gap 1.31m Hole: Air Background: YIG Rod: YIG Background: Air

  8. Beam Propagation (FDTD) Simulation of Photonic Crystals Rod: YIG Background: Air Hole: Air Background: YIG

  9. Aluminum Anodized Aluminum Oxide Al Pt Electrolyte Self Assembled Nanopores Stirrer Temperature Bath Self Assembled Nanopores in Aluminum Oxide Nanopore Fabrication

  10. Nanopore dimension control a=30nm, r=10nm a=100nm, r= 30nm

  11. Bandgap Simulation Bandgap for current pore dimensions corresponds to UV.
