Abstract. Containerless crystallization of benzophenone and containerless melting of a cycloolefin polymer were performed under magnetic levitation conditions. It was found that the growth mechanism changes from dendritic growth to facet growth with decreasing the supercooling degree in the crystallization of benzophenone. In the case of containerless melting and solidification of a cycloolefin polymer, spherical samples were obtained by a homogeneous heating in an electric furnace with a heatproof bore scope.

“…Although the superconducting magnet with a 360 mm room temperature bore was designed to generate the magnetic field of 10 T in the coil center, the superconducting magnet was restricted to excite to the magnetic field of 8.5 T in the hybrid magnet operation. As a result, we have already reported that the resultant field which added 19 T of the water-cooled resistive magnet to 8.5 T of the superconducting magnet was achieved 27.5 T [5,6]. In this paper, we discuss causes that the cryocooled superconducting magnet could not generate the designed magnetic field of 10 T. It was found that thermal problems due to the temperature rise of the superconducting coil obstructed to excite to the designed magnetic field.…”
