Advance velocities of steps on {211} and {110} faces of yttrium iron garnet: Theory and observations

摘要: Abstract In a previous paper it was shown how kinetical statistical mechanical sublattice model and the integrated Hartman-Perdok roughening theory, in which concept of connected net plays key role, could be integrated. This approach applied to complex (220) 1 garnet. Carrying out computer calculations, advance velocities steps different crystallographic directions dependence supersaturation were calculated phenomena interlaced explained. this described above is two alternative nets (211) 2 The kinetic equations are derived structures garnet presented. Advance for YIG crystals growing from lead oxide flux. Results compared with nets. Bond energies presupposition that faces form {322} PbO flux close their temperature. It agreement between observed anisotropy on both each other freedom choose attachment frequencies Fe 3+ Y ions very limited. growth fronts temperature decrease if increases.
