The magnetic properties of some spinels make them suitable for a number of applications, for example, as magnetic storage media or for magnetic resonance imaging.10 There are several techniques available for producing high surface area metal oxides, as recently reported by Landau,11 but in most of the cases, the high-temperature treatments needed to fabricate the spinels and perovskites lead to the sintering of the resulting particles, with the concomitant reduction in active surface area, typically in the range of a few square meters (
