Title: | MAGNETIC AND ELECTRICAL PROPERTIES OF MAGNETITE (FE3O4)-BASED FILMS AND DEVICES | Authors: | XIAO WEN | Keywords: | Magnetite, Fe3O4, Film, Nanocolumn, RRAM, DFT | Issue Date: | 4-Aug-2017 | Citation: | XIAO WEN (2017-08-04). MAGNETIC AND ELECTRICAL PROPERTIES OF MAGNETITE (FE3O4)-BASED FILMS AND DEVICES. ScholarBank@NUS Repository. | Abstract: | A combined experimental and first-principles study is performed to investigate and improve magnetic and electrical properties of magnetite (Fe3O4)-based films. Exceptional magnetic properties are achieved for Fe3O4-based films demonstrating great potential for high-frequency, magnetic and spintronic applications. Furthermore, Fe3O4-based spintronic and non-volatile memory (NVM) devices are developed for information storage. Wet-chemical thermal decomposition method grows epitaxial tetragonal Fe3O4-based films on MgO with high saturation magnetization above 1 Tesla and fabricates heterostructure of Fe3O4 nanocolumn film on Ni with spin-valve-like magnetoresistance (MR). This work deepens the understanding on the physical properties of Fe3O4 and opens up new opportunities to apply Fe3O4 in spintronic devices and next-generation non-volatile memories. | URI: | http://scholarbank.nus.edu.sg/handle/10635/137661 |
