Studies of Nanoconstrictions, Nanowires and Fe₃O₄ Thin Films Electrical Conduction and Magnetic Properties. Fabrication by Focused Electron/Ion Beam / [electronic resource] : by Amalio Fernandez-Pacheco. - XVI, 188 p. online resource. - Springer Theses .
Introduction -- Experimental Techniques -- Magnetotransport Properties of Epitaxial Fe3O4 thin Films -- Conduction in in Atomic-Sized Magnetic Metallic Constructions created by FIB -- Pt-C Nanowires created by FIBID and FEBID -- Superconductor W-Based Nanowires created by FIBID -- Magnetic Cobalt Nanowires created by FEBID -- Conclusions and Outlook -- CV.
This work constitutes a detailed study of electrical and magnetic properties in nanometric materials with a range of scales: atomic-sized nanoconstrictions, micro- and nanowires and thin films. Firstly, a novel method of fabricating atomic-sized constrictions in metals is presented; it relies on measuring the conduction of the device while a focused-ion-beam etching process is in progress. Secondly, it describes wires created by a very promising nanolithography technique: Focused electron/ion-beam-induced deposition. Three different gas precursors were used: (CH₃)₃Pt(CpCH₃), W(CO)₆ and Co₂(CO)₈. The thesis reports the results obtained for various physical phenomena: the metal-insulator transition, superconducting and magnetic properties, respectively. Finally, the detailed magnetotransport properties in epitaxial Fe₃O₄ thin films grown on MgO (001) are presented. Overall, the new approaches developed in this thesis have great potential for supporting novel technologies.
