The transport properties in ferromagnetic Fe-Ni and Ni nanorings below 4.2 K were reported. The Aharonov-Bohm oscillation and the universal conductance fluctuation were observed at 30 mK in a Fe-Ni nanoring. The estimated phase coherence lengths in a Ni nanoring was about 80 nm, which was much smaller than that in a Fe19Ni81 nanoring.
