%X In this paper, we report the investigation of nickel ultrafine particles (UFP) with surface oxide through the measurement of macro-magnetic properties. Besides the strong effective ani-stropy on the surface or/and the interface, we find that the nickel UFP, shows extra magnetization, which is contributed by the surface or/and the interface.
