Document Type and Number:
WIPO Patent Application WO/2019/184129
Kind Code:
A1
Abstract:
Disclosed is a magnet for the magnetic control of Czochralski single crystals, the magnet comprising multiple coils, wherein the multiple coils are connected in series and are arranged around the outer periphery of a single crystal furnace, two oppositely arranged coils of the multiple coils are arranged in a centrally symmetrical manner about the central axis of the single crystal furnace, and the central axis of each of the coils passes through the central point of the single crystal furnace; each of the coils comprises a main coil and a secondary coil which are coaxially arranged, and the secondary coil is provided further away from the single crystal furnace than the main coil; and when the coil is energized, the current direction in the main coil is the opposite to that in the secondary coil.
