Effect of gadolinium on magnetite exsolution in a garnet matrix
Description
Magnetite exsolves from a garnet matrix via a pretransformed nucleus when gadolinium is substituted for yttrium in yttrium iron garnet. The effect of gadolinium on the exsolution mechanism was studied by x-ray microanalysis using a transmission electron microscope; a strong decrease in gadolinium concentration was found within the petransformed nuclei. The ionic structure of the garnet lattice indicates that Ge3+ ions allow a shear process which leads to the petransformed nuclei, whereas with Y3+ ion diffusion is the only process for magnetite exsolution
