Abstract
PURPOSE: To eliminate the ununiformity of a crystal due to heat convection and to reduce the size and weight of the apparatus in a method for growing a crystal from a melt of an electrically conductive substance by pulling, by applying a sufficiently intense DC magnetic field symmetrically with respect to the center line of rotation of the melt.
CONSTITUTION: By electrifying a heating element 2, a melt 3 of a prescribed substance is prepared in a crucible 1, and a seed crystal 5 of a single crystal having a uniform crystal direction is placed on the center line 4 of rotation of the melt 3 and brought into contact with the melt 3. The support 6 of the crystal 5 is slowly pulled up to grow a single crystal 7 having the same crystal orientation as the crystal 5. At this time, a DC magnetic field 16 which is symmetrical with respect to the center line 4 and has ≥1,000 Oe intensity at the central part is applied to the whole or a part of the melt 3 by supplying DC 15 to a solenoid 14 concentric with the outer heating element 2.
