In this dissertation, I use sequential electron tunneling to study the differential conductance spectra and magnetic properties of single cobalt and nickel particles below 5 nm in diameter, and observe a wealth of material-dependent effects. The spin-orbit interaction is a key mechanism in the observation of a variety of effects, including giant electron spin g-factors and shifts in the anisotropy energy of the magnetic particle upon the addition of a single electron. I show how such effects can lead to an effective magnetization blockade, which allows for the voltage control of magnetic hysteresis. I model the quantum mechanical system characteristics using master equations, and propose a new type of spin-transfer torque device that relies on the magnetization blockade effect.\u003C\/p\u003E\u003Cp\u003E \u003C\/p\u003E","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":"","field_summary_sentence":[{"value":"Effects of the Spin-Orbit Interaction on Electron Tunneling in Single Ferromagnetic Nanoparticles"}],"uid":"27707","created_gmt":"2015-10-09 10:26:53","changed_gmt":"2016-10-08 02:14:18","author":"Tatianna Richardson","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2015-11-02T12:00:00-05:00","event_time_end":"2015-11-02T14:00:00-05:00","event_time_end_last":"2015-11-02T14:00:00-05:00","gmt_time_start":"2015-11-02 17:00:00","gmt_time_end":"2015-11-02 19:00:00","gmt_time_end_last":"2015-11-02 19:00:00","rrule":null,"timezone":"America\/New_York"},"extras":[],"groups":[{"id":"221981","name":"Graduate Studies"}],"categories":[],"keywords":[{"id":"100811","name":"Phd Defense"}],"core_research_areas":[],"news_room_topics":[],"event_categories":[{"id":"1788","name":"Other\/Miscellaneous"}],"invited_audience":[{"id":"78771","name":"Public"}],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[],"email":[],"slides":[],"orientation":[],"userdata":""}}}
