A magnetic material used to raise the magnetic field application of a single crystal, and a method of raising the magnetic field application of a single crystal.

摘要

The present invention is provided with a plurality of coils, the plurality of coils are connected in series, and are arranged so as to surround the outer periphery of the single crystal furnace. The coils are arranged symmetrically with respect to the central axis of the single crystal furnace, and the central axes of the coils pass through the center point of the single crystal furnace, and each coil includes a primary coil and a secondary coil coaxially arranged. The secondary coil is arranged away from the single crystal furnace with respect to the primary coil, and when the coil is energized, the current direction in the primary coil and the current direction in the secondary coil are opposite. A magnetic material used for pulling up a magnetic field is disclosed. A method of pulling a single crystal magnetic field is further disclosed.
