The relaxation phenomena near $T_{\text{N}}$ in Co(HCOO)22H2O have been studied by means of AC magnetic susceptibility with frequency of 7 Hz${\sim}$1 MHz. The relaxation phenomena which are due to the magnetic domain or the spin cluster motion have been detected clearly and studied. The relaxation effect of the magnetic domain motion can be separated out from the "intrinsic" susceptibility peak which comes from the phase transition, by applying the small external static magnetic field, and/or by using the relatively high frequency. The relaxation of the magnetic domain motion affects the "intrinsic" susceptibility of the phase transition even above the transition temperature. So called "critical slowing down" or "critical speeding up" in the crystal would have been observed in much higher frequency than 1 MHz.
