Studies on magnetic properties of unique molecular magnet {Fe~Ⅱ(pyrazole)42Nb~Ⅳ(CN)_8-4H_2O}_n

摘要

In this paper magnetic properties of hybrid inorganic-organic compound{[Fe~Ⅱ(pyrazole)_4]_2[Nb~Ⅳ(CN)_8]?4H_2O}n are presented. This is a three dimensional molecular magnet with well localized magnetic moments, which make it a suitable candidate for testing magnetic models. In order to characterize the magnetic properties of- the above compound we performed the AC/DC magnetometry in the range 0-5 T. The special attention was paid to the phase transition at 7.9 K. The study in magnetic field supports magnetic ordering below 7.9 K.
