  1. 1. Bismuth iron garnet films for magneto-optical photonic crystals

    Författare :Sören Kahl; KTH; []
    Nyckelord :Faraday effect; iron garnet; pulsed laser deposition; photonic crystals;

    Sammanfattning : The thesis explores preparation and properties of bismuthiron garnet (BIG) films and the incorporation of BIG films intoone-dimensional magneto-optical photonic crystals (MOPCs). Films were prepared by pulsed laser deposition. LÄS MER

  3. 2. Fibre Optic Magnetic Field Sensors Utilizing Iron Garnet Materials

    Författare :Hans Sohlström; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; yig; iron garnets; rare earth garnets; magneto-opics; optical waveguide; fibre optical sensors; magnetic field measurement; current measurement;

    Sammanfattning : This thesis deals with the subject of fibre optic magnetic field sensors utilizing iron garnet materials. Such materials exhibit a large Faraday rotation which make them advantageous for application in compact mag­netic field sensors. LÄS MER

  4. 3. Complex Oxide Photonic Crystals

    Författare :Dzmitry Dzibrou; Alex Grishin; Peter Lazor; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Photonic crystals; magneto-optical effects; refractive index; iron garnet; Optics; Optik;

    Sammanfattning : Microphotonics has been offering a body of ideas to prospective applicationsin optics. Among those, the concept of photonic integrated circuits (PIC’s) has recently spurred a substantial excitement into the scientific community. Relisation of the PIC’s becomes feasible as the size shrinkage of the optical elements is accomplished. LÄS MER

  7. 5. Hydrogen diffusion and storage mechanisms in diopside

    Författare :Rickard Sundvall; Henrik Skogby; Alasdair Skelton; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mineralogy; Mineralvetenskap; mineralogi; petrologi och geokemi; Mineralogy; Petrology and Geochemistry;

    Sammanfattning : Hydrogen is a widespread trace element in many nominally anhydrous minerals (minerals without water or hydroxyl ions in their structural formula) from the Earth's crust and mantle. The hydrogen is normally incorporated in the form of hydroxyl ions and can be regarded as structurally bound water. LÄS MER
