Outline of Final Research Achievements

In order to clarify the factors that cause magneto-elastic effects and other phenomena in ferromagnetic iron-based alloys, magnetostriction, reverse magnetostriction, elasticity, etc. were investigated using Fe-Ga alloy single crystals. Focusing on the anisotropy of magnetostriction and reverse magnetostriction due to the application of external magnetic field and stress, the relationship between the microscopic processes of magnetostriction and reverse magnetostriction and the magnetization process was investigated by magnetic domain observation and other methods. The characteristic magnetic domain wall motion induced by an external field on alloy single-crystals is related to the vibrational energy harvesting characteristics. The domain wall motion due to the external field corresponded to the magnetic flux change by the alloy, and was related not only to magnetostriction and inverse magnetostriction but also to electromagnetic induction.

Academic Significance and Societal Importance of the Research Achievements

磁歪合金や軟磁性合金は振動発電に用いる材料として注目されているが、その発電機構については不明な点が多かった。本研究では、その発電機構の基礎となる外部の磁場や応力による磁区構造の変化、それらと磁歪や逆磁歪との対応などに関して検討し、振動発電分野等に必要な基礎的知見を得た。例えば異なる種類の磁壁の外場による応答性の特徴を解明し、磁壁運動は磁束変化、磁歪や逆磁歪の発生に対応することを示した。これらの成果は特定方位の大型Fe-Ga合金単結晶を振動発電に用いる上での重要な情報であり、磁場と合金との相対運動による電磁誘導の発電への寄与も明らかにできたので、環境発電技術等への貢献度は大きい。
