  • Parametric Pumping of Spin Waves Using Acoustic Waves

    Creator:
    Chowdhury, Pratim
    Abstract:
    Spintronics is an emerging field of research wherein the electron spin instead of, or along with, the conventional electron charge may be utilized in developing next generation logic devices. One of the most promising aspects of spintronics is that information transfer may be achieved by spin waves in logic devices,...

  • Determination of magnetoelastic parameters in magnetic thin films from FMR spectra

    Creator:
    Masood, Khalid I.
    Abstract:
    The ferromagnetic resonance (FMR) phenomenon serves as a sensitive probe of the effective internal fields in a magnetic material. FMR spectroscopy has consequently become a well-established technique, extensively employed in assessing material properties such as magnetic anisotropy, Landé g-factor, damping parameter, and the magnetoelastic constants of magnetic materials. Determining these...

  • Robotic Actuation and Control with Programmable, Field-Activated Material Systems

    Creator:
    Bira, Nicholas P.
    Abstract:
    This dissertation presents novel, field-activated smart material systems for the actuation and control of autonomous robots. Smart materials, a type of material whose properties can be changed with an external stimuli, represent a promising direction to expand upon existing robotic control and actuation methods, particularly in the sub-fields of soft...

  • Soft Magnetic Composites for High Frequency Applications

    Creator:
    Song, Han
    Abstract:
    Soft magnetic composites, consisting of fine metallic particles in a non-magnetic, insulating matrix, have great potential for integrated inductor and antenna applications. The dielectric and magnetic properties of soft magnetic composites can be tailored by the choice of matrix as well as particle composition, size, and concentration for reduction in...

  • 1/f noise of GaAs resistors on semi-insulating substrates, and 1/f noise due to temperature fluctuations in heat conduction

    Creator:
    Choi, Mun-Seork
    Abstract:
    This research work focuses on the mechanism of 1/f noise in GaAs resistors on semi-insulating substrates and 1/f noise due to temperature fluctuations in heat conduction in resistors, diodes, and bipolar transistors. The goal of this research is to generate accurate models to explain physical origin of 1/f noise in...

  • Systemically Delivered Magnetic Hyperthermia for Cancer Treatment

    Creator:
    Albarqi, Hassan Ahmad M.
    Abstract:
    Despite advances in treatment, cancer remains among the leading causes of death in the world. Progress in the treatment of metastatic cancers was seen with chemotherapy and radiotherapy, however, the major drawbacks of conventional cancer therapies are limited efficacy and severe side effects. Magnetic fluid hyperthermia (MFH) is a new...

  • Modeling, Fabrication, and Characterization of Magnetic Thin Films for Integrated Inductor and MRAM Applications

    Creator:
    Buford, Benjamin
    Abstract:
    Magnetic thin films have potential to improve devices such as on-chip inductors, and enable new technologies such as magnetic random access memory (MRAM). The use of magnetic cores in on-chip inductors is typically limited to applications well under 1 GHz. At higher frequencies, the performance of the magnetic core is...

  • A study of the dynamics and rheology of passive and active suspensions of particles with various geometries

    Creator:
    Tan, Mingyang
    Abstract:
    Suspensions of particles in fluids are everywhere in our life, such as paints, pharmacies, food, etc. Suspensions can exhibit properties that common fluids do not possess. For example, the paint needs to flow well when brushing so that it can be smeared on the wall, which is aided by the...
