We investigated the possibility of metastable phase formation and functional properties of the magnetic system accompanied with floating melt solidification of materials by using the electromagnetic levitation apparatus. Expected for a microgravity experimental apparatus used in an airplane, and then we established and studied the basic technique of this apparatus in detail. As a result, the crystallization of ferromagnetic metastable phase with the high coercive force unreported until now was obtained in the containerless floating melt solidification sample of the Nd-Fe binary alloy. In addition, we investigated the non-equilibrium solidification process in a new high speed cooling curve measurement system and a new result was obtained.
