Outline of Final Research Achievements |
In order to investigate the potential of a material processing in high magnetic fields, a prototype apparatus that can perform the physical vapor transport method in magnetic fields was developed, and demonstration experiments were performed with this apparatus using urea as a sample in high magnetic fields and magnetic force fields. As a result, the position of crystallization was found to be affected by the magnetic force direction and strength, which means the position of crystallization will be controlled by the magnetic field. This also suggests the possibility of controlling the behavior of the vapor phase by magnetic forces.

Academic Significance and Societal Importance of the Research Achievements |
磁場中物理気相輸送法によって析出する結晶の位置が磁気力の影響を受けるということは,成長空間の温度勾配に加えて磁気力によっても析出位置を制御できる可能性を示している.磁場に対する応答が弱い反磁性物質に対しても明確な磁場,磁気力の影響が示されたことで,大半が反磁性である有機材料に対しても磁場中プロセスを利用することで新奇材料の作製が期待できる.
