Abstract

The low-temperature magnetoresistance in ferromagnetic Ni and Fe19Ni81 nanorings were studied. Although the aperiodic fluctuation and the periodic oscillation were observed in Fe19Ni81 nanoring, the periodic oscillation disappears in Ni nanoring. The estimated phase coherence length in Ni nanoring is about 80 nm, which is much smaller than that in Fe19Ni81 nanoring (∼500 nm). These results imply that there exists a mechanism, such as coupling between conduction electron and local magnetic anisotropy.
