The field-cooled (FCM) and zero-field-cooled (ZFCM) magnetization of ferromagnetic fine cobalt particles in a Cu_<97>Co_3 alloy has been studied. The spin-glass-like temperature dependence of the magnetization has been observed ; ZFCM exhibits a spin-glass-like maximum (at T_p) and FCM is larger than ZFCM at low temperatures. However, the difference between FCM and ZFCM obviously exists far above T_p. Furthermore, FCM increases monotonically with decreasing temperature even below T_p while that of typical spin glasses is nearly independent of temperature. The analysis of the magnetization shows that the temperature dependence of FCM and ZFCM of Cu_<97>Co_3 is well described on the basis of the superparamagnetic blocking model with no interaction between the particles, whereas that of a typical spin-glass Au_<96>Fe_4 cannot be explained by the blocking model.
