In this Letter, we report a viable solution to this problem, utilizing a 6-nm-thick epitaxial Fe3O4 thin film on GaAs(100), where the fourfold magnetocrystalline anisotropy is negligible. We demonstrate that in the Fe3O4 planar wires patterned from our thin film, such a unique magnetic anisotropy system has been preserved, and relatively simple magnetic domain configurations compared to those previous reports can be obtained. © 2014 Author(s). | Source Title: | AIP Advances | URI: | https://scholarbank.nus.edu.sg/handle/10635/183654 | ISSN: | 21583226 | DOI: | 10.1063/1.4897963 | Rights: | Attribution 4.0 International |
