Data for Nanocrystalline transition-metal gallium oxide spinels from acetylacetonate precursors via solvothermal synthesis

In the case of iron, higher amounts of the transition metal can be included to give a Fe:Ga ratio of 1:1. Elemental mapping using energy dispersive X-ray spectroscopy on the TEM, however, reveals inhomogeneity in the distribution of the two metals. This is consistent with variable temperature 57Fe Mössbauer spectroscopy that shows the presence of Fe2+ and Fe3+ in more than one phase in the sample.

Variable temperature magnetisation and electron paramagnetic resonance (EPR) indicate the presence of superparamagnetism at room temperature in the iron-gallium oxides.<br><br>Data are ascii format with names corresponding to the figures in the main paper, as follows: Figure1a powder XRD data Figure3a powder XRD data Figure5a powder XRD data Figure 7a magnetisation data Figure 7a magnetisation data Figure 8a Magnetic hysteresis data Figure 8b Magnetic hysteresis data Figure 9a EPR spectral data Figure 9b EPR spectral data Figure 10a Mossbauer spectral data Figure 10b Mossbauer spectral data Figure 10c Mossbauer spectral data Figure 10d Mossbauer spectral data
