Magnetic Behaviour of NiFe-Hexacyanates as Influenced by Change of Ligand

Abstract Two new ferromagnets belonging to the Prussian Blue family have been synthesized : [Ni(OCH2CH2O)2]3[Fe(CN)6]2.2.5H2O (I) and [Ni(SCH2CH2O)2]3[Fe(CN)6]2.7H2O (II), with respective Curie temperatures 21K and 23 K. Their synthesis, and magnetic properties are reported. One of them exhibits a coercive field as high as 1792 Oe.
