Magnetic Damping of Thermocapillary Convection in the Floating-Zone Growth of Semiconductor Crystals
… research has been conducted in the area of the magnetic damping of thermocapillary convection in floating zones. Both steady and unsteady flows have been investigated. Due to the added complexities in solving Maxwells equations in these magnetohydrodynamic problems and due to the thin boundary …

EMERGENT PHENOMENA AND NOVEL DEVICES BASED ON SPIN-ORBIT COUPLING AT COMPLEX OXIDE INTERFACES
… an effective means to drive and manipulate magnetic properties – such as anisotropy, spin relaxation, magnetic damping, anisotropic magnetoresistance, and anomalous Hall effect – allowing it to be exploited for future spin-orbitronics, especially for the logic-in-memory computing with …

Electrical Manipulation of Spin Dynamics in Ferromagnetic Multi-layers
This thesis explores spin-detection in ferromagnetic materials via two different mechanisms that drive the ferromagnetic resonance – the charge-spin conversion via inverse spin-Hall effect induced by an external charge current and the photon-magnon coupling between ferromagnetic structures and …

A Single-Stage Passive Vibration Isolation System for Scanning Tunneling Microscopy
… and the STM stays on top of the copper stage. Magnetic damping with neodymium magnets, which induces eddy currents in the copper conductor, is the primary damping method to reduce the vibrations transferred to the mass-spring system. FEMM and MATLAB® are used to model magnetic flux density and …

Ferromagnetic dynamics in coupled systems
In this work, ferromagnetic thin films coupled strongly to other physical subsystems (magnetic or otherwise) are studied, and the effect this coupling has on their static and dynamic properties is investigated in order to understand both the ferromagnets themselves, and the systems they are coupled …

Multi-Scale Model of the Stability of a Laterally Heated Liquid Bridge Under the Influence of an Axial Magnetic Field
… the crystal. This study investigates the use of magnetic fields in suppressing these instabilities. When a crystal is grown in the presence of a magnetic field, electric currents are generated in the conducting melt. These currents interact with the magnetic field, producing Lorentz body forces, …

Pulsed Laser Deposited Iron Garnet Thin Films for Spintronics
… spintronic memories because of their low Gilbert damping and their growth with perpendicular magnetic anisotropy (PMA) which promote fast domain wall dynamics. Additionally, selection of rare earth ion and substitution of cations in various sublattices of iron garnets enables tuning of their …

Development of Novel Eddy Current Dampers for the Suppression of Structural Vibrations
… aberrations. One potential method of applying damping to the membrane structure is to use magnetic damping. Magnetic dampers function through the eddy currents that are generated in a conductive material that experiences a time varying magnetic field. However, following the generation of these …
