  • Applications of Magnetic Materials in Soft Robotics

    Creator:
    Davis, William M.
    Abstract:
    Magnetic materials can be used in modern soft robotics as a method for external stimulus actuation and motion control. By combining aspects of biology and mechanics, devices are fabricated to create a structure capable of complex movement. Applications that these devices are subject to can be broken down into four...

  • 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...

  • Magnetic Properties of Polymer Nanocomposite Materials Prepared using Multi Jet Fusion 3D Printing Methods

    Creator:
    Cannamela, Madeleine G.
    Abstract:
    The goal of this research was to explore if an inkjet 3D printing technology, known as Multi Jet Fusion (MJF), could be used to fabricate magnetic polymer nanocomposites with systematically varied volume fractions of magnetic nanoparticles. Soft magnetic nanoparticles were chosen because of their applications in communications technologies and other...

  • Field-Free Precessional Magnetization Switching by Focused Surface Acoustic Waves

    Creator:
    Lin, Han-Ting
    Abstract:
    In this research, the possibility of the precessional magnetization switching by focused surface acoustic waves, without external magnetic field, has been demonstrated. The technique of generating an effective magnetic field by applying stress to a magnetostrictive material via a surface acoustic wave is applied to perform field-free magnetization switching. It...

  • 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...

  • Silicon Microring Resonator Driven by High-Mobility Conductive Oxide Capacitor

    Creator:
    Hsu, Wei-Che
    Abstract:
    Silicon photonics has rapidly become one of the most promising photonic integration platforms. Especially, microring resonator (MRR) plays a pivotal role in silicon photonics and has been widely used for electro-optic (E-O) modulators and wavelength filters due to its small footprint, low energy consumption, and high quality factor (Q-factor). Recently,...

  • Frequency-Dependent Rheological Characterization of Viscoelastic Materials Using Magnetic Nanoparticle Probes

    Creator:
    Myers, Renee C.
    Abstract:
    Extending rheological characterization methods to very small length scales is of interest. AC susceptometry using magnetic nanoparticle probes has been proposed for measurement of frequency-dependent rheological properties at the nanoscale. As this technique has been primarily used for ideally Newtonian fluids, this research aimed to extend this technique to viscoelastic...
