Single crystal manufacturing method, magnetic field generator, and single crystal manufacturing apparatus

A single crystal manufacturing method for pulling-up a single crystal while applying a lateral magnetic field to a melt in a crucible, comprising:

• lifting the crucible in accordance with a reduction in the melt during a crystal pull-up process;
• and
• controlling a magnetic field distribution in accordance with the reduction in the melt so as to make a constant direction of the lateral magnetic field at a melt surface and to make a constant direction of the lateral magnetic field at an inner surface of a curved bottom portion of the crucible from a start to an end of a body section growing step of the single crystal, wherein
• the direction of the magnetic field at the melt surface is parallel to the melt surface,
• a rotary axis of the crucible is defined as Z-axis,
• a magnetic field center axis of the lateral magnetic field orthogonal to the Z-axis is defined as Y-axis,
• an intersection between the Z-axis and the Y-axis is set to an origin,
• an axis orthogonal to a YZ plane and passing the origin is defined as X-axis, and
• an angle θ formed by a normal vector of the inner surface and a magnetic field vector on an intersection line between the inner surface of the curved bottom portion of the crucible and the YZ plane is maintained at equal to or more than 75° and equal to or less than 105°.
