Abstract
Thermal decomposition of the trinuclear heterometallic oxoacetates [Fe
2M(μ
3-O)(CH
3COO)
6(H
2O)
3] has been used as a single-precursor method for synthesis of the spinel-structured ternary oxides MFe
2O
4 (M
=
Mn
II, Co
II, and Ni
II). This facile process occurring at 320
°C results in the formation of nanocrystalline (7–20
nm) highly pure stoichiometric ferrites in quantitative yield. The magnetic properties of these nanoparticulate ferrites were studied in the 10–300
K temperature range, revealing superparamagnetic behavior for the Ni and Mn particles and ferrimagnetic behavior for the Co ones at room temperature. Their blocking temperatures follow the order: CoFe
