The Melting of glass materials levitated in high magnetic fields has been carried out without a crucible by using a hybrid magnet and a CO 2 laser. A cubic glass with 6 mm sides has become a complete sphere through melting and cooling in the air. This new method will provide opportunities for obtaining high-purity and new heterogeneous materials.

Construction of large scale Bitter magnet and its application to crystal growth in levitating water

IEEE Transactions on Applied Superconductivity (2000)

M. Mctokawa Satoshi Awaji S. Miura M. Hamai Iwao Mogi

Large scale Cu-24%Ag plates have been developed for high field Bitter magnets. Using these plates, we have succeeded in constructing a double Bitter magnet for 30 T hybrid magnet with 32 mm room temperature bore. This double Bitter magnet successfully generated 19 T under the back-up field of 11.1 T by a large bore superconducting magnet. Current and power for the water cooled magnet are about 21.3 kA and 6.9 MW, respectively. Using this 30 T hybrid magnet, we have performed crystal growth of NH/sub 4/Cl in water levitated by a magnetic field. It has been shown that only one crystal grows in such a levitating condition and nucleation of the crystal is strongly suppressed in a magnetic field different from the normal condition.

Alignment and Orientation of Diamagnetic Materials under Magnetic Levitation Condition

Japanese Journal of Applied Physics (2001)

M. Hamai Iwao Mogi Satoshi Awaji Kazuo Watanabe M. Motokawa

The behavior of levitating diamagnetic materials is investigated in gradient magnetic fields produced by a hybrid magnet. The levitating alignment of bismuth particles and the levitating orientation of a paraffin rod are reported, and these behaviors are discussed based on their potential energy curves in the magnet, the interaction among diamagnetic moments and the shape anisotropy.
