Modification of the top-seeded growth from high temperature solutions

A new modification of the top-seeded growth from high temperature solutions (HTS), allowing simultaneous application of the accelerated crucible rotation technique (ACRT), was developed. The platinum crucible containing the flux was equipped with the platinum reflectors bearing the holder of the seed. A particular interest was devoted to the optimization of the temperature distribution in the flux and to the ACRT program. The apparatus was tested by the growing of YIG: Mn single crystals on the seeds orientated in [111], [110] and [211] directions.
