Abstract
A study is made of the effects of a vertical magnetic field on thermal symmetry in a Czochralski silicon melt. By application of a magnetic field of 2500 Oe, thermal asymmetry is reduced to about 1/2 that at 0 Oe, and isothermal contours become concentric circles. A model is proposed where a vertical magnetic field suppresses asymmetric thermal convection which degrades thermal symmetry, and heat transfer in the stagnant melt is dominated by symmetric heat conduction.Keywords
