A new vertical magnetic field applied LEC apparatus has been developed for volume production of large size GaAs single crystals. The apparatus consists of a superconducting magnet with compact refrigerator systems and an in-house modified high pressure puller. Temperature fluctuation through the molten GaAs was suppressed to less than 0.3°C by the application of more than 1000 Oe. The vertical magnetic field effects on GaAs melt are described in comparison with the results of a transverse magnetic field.
