  • Electrical characterization of thermally reduced graphite oxide

    Creator:
    Jewell, Ira
    Abstract:
    This thesis describes the transport properties observed in thermally treated graphite oxide (GO), which holds promise as an economical route to obtaining graphene. Graphene is a material consisting of a single atomic plane of carbon atoms and was first isolated as recently as 2004. Several isolation techniques have been investigated,...

  • A fabrication study of surface acoustic wave devices for magnetic field detection

    Creator:
    Chin, Matthew L.
    Abstract:
    Surface acoustic wave (SAW) sensors are versatile devices that can be configured to sense a variety of measurands such as temperature and pressure. The potential use of surface acoustic wave devices for magnetic field detection is explored in this study. Compared to current magnetic field sensors, a sensor based on...

  • Characterizing spin-orbit torques in β-W/Ta/CoFeB/MgO devices

    Creator:
    Allen, Shane R.
    Abstract:
    Materials with a strong spin Hall effect and Rashba-Edelstein effect have the potential to improve the efficiency of solid-state magnetic memory technologies and other magnetic logic devices. Heavy metals have been identified as having these properties, including the beta crystal phase of tungsten. In this work, we determine the strength...

  • Designing bulk acoustic wave resonators for parametric amplification of spin waves

    Creator:
    Chowdhury, Pratim
    Abstract:
    Spintronics is an emerging field of research dealing with devices that can potentially exploit the additional degree of freedom provided by the electron spin along with or instead of the conventional electronic charge. One of the most promising aspects of spintronics is the potential use of magnetostatic spin waves as...

  • A Micro Scale Magnetic Particle Imaging System

    Creator:
    Lenox, Philip A.
    Abstract:
    Magnetic particle imaging (MPI) is a biomedical imaging technique which detects the presence of magnetic nanoparticles which have been introduced into the specimen prior to imaging. MPI has shown promise for real-time imaging with spatial resolution comparable to magnetic resonance imaging (MRI). MPI research has focused predominantly on the development...

  • Magnetically programmable surface acoustic wave devices for RFID applications

    Creator:
    Chin, Matthew
    Abstract:
    Magnetically programmable surface acoustic wave (MP SAW) devices were designed, fabricated and characterized in this thesis using integrated giant magnetoresistive (GMR) bits with interdigital reflectors. This provides a proof of concept of a novel storage element on radio frequency identification tags. Interdigital transducers (IDTs) on a piezoelectric substrate are used...

  • A Microwave Signal Correlator Based on Parametric Pumping of Spin Waves

    Creator:
    Hansen, Mikkel N.
    Abstract:
    This work demonstrates correlation of microwave signals encoded with 16-bit codes using the parametric interaction of spin waves. Signal processing correlators are devices that compare two signals, such as a reference code and a received code, where the output indicates the similarity between the signals. Correlators are used in communication...

  • Printing 3D Magnetic Composite Structures with Arbitrary Anisotropy using UV-curable Magnetic Ink

    Creator:
    Clay, Garrett
    Abstract:
    Inkjet printing offers a cost effective, highly customizable method for rapid manufacturing of functional devices with minimal material waste. Although this method has been used for a variety of composites, little work has been done in the area of 3D printing magnetic composites. Presented here is a process for inkjet...
