We present the study of AC susceptibility and DC magnetization of KCoI
I[Fe-III(CN)(6)]. The results show an evidence of the magnetic orderin
g below 13.7 K. The strong frequency dependence of the AC susceptibili
ty and a non-linear susceptibility was observed. The coercive field of
the magnetization hysteresis loop measured at 4.2 K was 900 Oe. The s
ystem shows glassy features, probably due to crystalization water and
some structural disorder in the sample. (C) 1998 Elsevier Science B.V.
