Spin-reorientation transition in ɛ-In0.24Fe1.76O3 nanowires

The magnetic phase transition in ɛ-In 0.24 Fe 1.76 O 3 nanowires at a temperature of 190 K, which is accompanied by a sharp decrease in the magnetization and coercive force, has been discussed. A mechanism of the observed transition associated with a change in the direction of the easy magnetization...

Zusammenfassung:The magnetic phase transition in ɛ-In 0.24 Fe 1.76 O 3 nanowires at a temperature of 190 K, which is accompanied by a sharp decrease in the magnetization and coercive force, has been discussed. A mechanism of the observed transition associated with a change in the direction of the easy magnetization axis owing to the competition between single-ion and dipole-dipole magnetic anisotropies has been proposed.
