Easy Axis Spin-Flop in ε-Phase In-Doped Iron (III) Oxide Nanowires


Article Preview

This work reports study of magnetic properties of the ε-In0.24Fe1.76O3 nanowires possessing 6 kOe coercive force at room temperature. Freezing of the sample below 190 K causes sharp decrease of the coercive force and magnetization of nanowires driven by the easy axis spin-flop transition.
