Abstract

<abstract> <title> <x content-type="archive" xml:space="preserve">Abstract</x> </title> <p>The mixed metal oxalate bridged compounds NBu₄M_A^II_nFe^II_1–n[Fe^III(ox)₃](M_A = Mn, Zn) were investigated by magnetic measurements. The temperature dependence of the compounds NBu₄Zn^II_nFe^II_1–n[Fe^III(OX)₃] (<italic>n</italic> = 0. 04, 0·08, 0·10) shows two temperature compensation points in the temperature range of 32–41·5 K and multiple magnetic pole reversals are observed in the material. When <italic>n</italic>≧0·1 the temperature compensation point disappears, the value of M increases and exhibits weak irreversibility in the field cooled (FC) magnetisation curves. At the same time, spin glass state is founded below 35 K and the bifurcation of the zero field cooled and FC plots below the Neel temperature of 30 K indicates irreversibility. At the Neel temperature of 39·9 K, a compensation temperature and a spin canting are observed in the compound NBu₄Fe^II_0·97Mn^II_0·03[Fe^III(OX)₃].</p> </abstract>
