A Study of Hairpin Bubble Generating Circuits and Strip Domain Shapes

Abstract

<p>A mathematical model which describes the forces acting on the domain walls of a strip domain as they are pushed together under the influence of an externally applied field is developed and presented in the thesis.</p> <p>Photographs are presented of actual domains as their walls are pushed together by the field due to current flowing in a hairpin conductor circuit.</p> <p>The photographs of wall shape are compared with wall shapes predicted by a computer program which was based on the mathematical model.</p> <p>Possible extensions to the model are proposed which would make it a useful tool for designing an optimal bubble cutter.</p>
