Abstract
The temperature for preparation of garnet phase of the conventional yttrium or rare-earth iron garnet can be lowered by about several hundreds centigrade by substituting 24C site of the garnet by lead. Thus obtained lead-substituted yttrium or rare-earth iron garnet has greater specific Faraday rotation than lead-nonsubstituted yttrium or rare-earth iron garnet.
