Faceting of (YEuYbCa)3(GeFe)5O12 on LPE garnet films

The correlations of the faceting on LPE films and the lattice mismatches between LPE films and GGG substrates were investigated, taking into consideration LPE growth conditions for (YEuYbCa)3(GeFe)5O12 in a PbO.B2O3 flux. The facets in this garnet system appeared, even when the mismatches were very small. In the case of a small mismatch, it was found that the tendency to faceting increased with increase in the lattice constants of LPE films and decrease in their growth rate. However, no defects such as a dislocation were observed in the faceting on LPE films using the X-ray reflection topography method. The lattice mismatches caused no harmful effects to the characteristics of bubble domains such as magnetic domain wall coercivity, domain wall energy and mobility, and it also did not effect magnetic bubble propagation
