“…Here, for example, observed broadening of the SiO 4 stretching modes is consistent with an {Fe 2+ (1) + Fe 2+ (2)} exchange energy of 4.7 cm À1 derived from inelastic neutron scattering and far-infrared measurements [24]. Magnons in fayalite occur at low energies and they have also been studied using FTIR methods [25,26]. FIGURE 2.…”

“…Indeed, we are not aware of any low temperature heat capacity investigation of any Fe-Mg silicate solid solution. Although most magnetic interactions (e.g., magnons) in silicates are rather weak [25,26], they should manifest themselves in low-temperature heat capacity behaviour.…”
