Nanofabrication Methods Towards a Photonically-Based Torque Magnetometer for Measurement of Individual Single-Crystalline Yttrium-Iron-Garnet MicrostructuresDownload
This thesis describes preparation and nanofabrication of single crystalline yttrium-iron-garnet (YIG) for the purposes of ultra-clean torque magnetometry, as well as the design, fabrication, and testing of photonic crystal-based nanoelectromechanical systems for sensing applications. A focused...
Electro-transmittance of molecular junctions was characterized electrically and studied optically at 410nm and 532nm. Between 1kHz and 100kHz there was no qualitative difference between the control samples and the molecular junction samples, however there were difficulties with reproducibility of...
The procedure for milling micrometre scale cantilevers of lutetium iron garnet using a focused ion beam microscope was developed. The infrastructure to study these cantilevers using rotational hysteresis loops and ferromagnetic resonance experiments was set up. The cantilevers were shown to...
The focus of this thesis is on electro-osmotically pumped flow of viscoelastic fluids through microchannels. Fluid transport in microscaled structures is typically laminar due to the low Reynolds numbers involved. However, it is known that viscoelastic polymeric liquids can display striking...
Optomechanics, the sensing of mechanical movement using optical modes, has seen great advancement in recent years and has been used for its high displacement sensitivity to couple to a variety of mechanical devices. Torsional devices have historically been used for measuring de Haas-van Alphen...
Nanomechanical torque magnetometry is emerging to become one of the most highly-sensitive methods for measuring magnetostatic interactions in mesoscopic magnetic materials. Here, advances in torque magnetometry are offered for the probing of new physics and extending the functionality of the...
Nanomechanical beam resonators show much promise for use in integrated on-chip mass sensing systems. This follows from their own very small masses and also their ability to store the mechanical energy of their oscillations to produce strong measurable mechanical response signals. To achieve...
Phase retrieval in the transmission electron microscope offers the unique potential to collect quantitative data regarding the electric and magnetic properties of materials at the nanoscale. Substantial progress in the field of quantitative phase imaging was made by improvements to the technique...
