Beschreibung
Zusammenfassung:The magnetic phase transition in ζ-[In.sub.0.24][Fe.sub.1.76][O.sub.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.
