AC susceptibilities of Mn(HCOO).2H.0 were measured to investigate aphenomenon of the fluctuation of uniform magnetization near the critical fern-perature (7'..::3.686K) under extremely weak magnetic field (temperatureBarkhausen effect). As the phenomenon has sttggested the movement of thecomplicated domain structure in the course of development of the spontaneousmagnetization, the measurements were made in three alternative conditions whichgive different domain patterns. We found that the susceptibility has a large peakaround T. and a long tail below T. in the same condition of observing the T.B.E.fluctuation. Co(HCOO).2H.0 was also examined as a salt having differentsymmetry type of interaction from that of Mn(HCOO).2H.0. Small but sharpspikes were observed in the uniform magnetization in the c:ourse of decreasingtemperature.
