Abstract

The magnetoresistance of a ferromagnetic Fe19Ni81 ring with 420 nm in inner diameter and 500 nm in outer diameter was measured at 4.2 K and 30 mK. When the magnetic field is applied to the ring, the magnetoresistance exhibits a periodic oscillation due to the Ahoronov Bohm effect in both a single domain configuration and a multi-domain configuration. This indicates that the interference effect of a conduction electron in the submicron ferromagnet subsists even in the strong modulation of local magnetization.
