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...

Masters Thesis
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...

Masters Thesis
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...

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...

Masters Thesis
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...

Masters Thesis
Design and Implementation of an Alternating Current Susceptometer for Measuring Brownian Relaxation Time of Magnetic Nanoparticles Suspended in a Liquid Medium

Creator:

Paul, Partha Sarathi

Abstract:

In this work, an alternating current (ac) magnetic susceptometer is designed and implemented to track the Brownian relaxation time of magnetic nanoparticles that are suspended in a liquid medium. The detection technique based on the Brownian relaxation time of magnetic nanoparticles has found its way in a variety of biosensing...

Capstone Project
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,...

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...

Masters Thesis
Acoustically Assisted Magnetic Recording

Creator:

Li, Weiyang

Abstract:

In the past few decades, magnetic recording has been used as a dominant solution for massive data storage due to its large capacity, excellent reliability and low cost. Nowadays, exponentially increasing user-generated information is creating a huge demand as well as great challenges for high density data storage solutions. For...

Dissertation
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...
