Magnetic and Electrical Characterizations of Half-Metallic Fe3O4 Nanowires

The magnetic properties of magnetite (Fe3O4) nanowires are investigated by means of electron holography, which deduces the magnetic information from the phase shift of electrons. The magnetic flux is parallel to the longitudinal axis of the nanowires (see figure). Observations on the magnetization d...

description The magnetic properties of magnetite (Fe3O4) nanowires are investigated by means of electron holography, which deduces the magnetic information from the phase shift of electrons. The magnetic flux is parallel to the longitudinal axis of the nanowires (see figure). Observations on the magnetization distribution reveal the possibility of regulating the spin current with the half‐metallic nanowires, owing to the controlled magnetization distribution in the 1D form.
