Outline of Final Research Achievements

For FeRhPd magnetic alloys, we performed the MCE measurement with Russian research group and published on Appl.Phys.Lett. XAFS measurements for FeRhPd alloys and presented at 17th International XAFS conference. For perovskite compounds, we analyzed RMC method to apply EXAFS analysis for SrTiO3 with Latvian research group and presented in 17th International XAFS conference. we published this research in J.Rad.Phys.Chem.

Academic Significance and Societal Importance of the Research Achievements

本研究におけるテーマはFeRhおよびfeRhPd磁性合金お構造相転移に関する基礎研究であり、次世代の磁気冷却機への応用が期待される材料に関する研究であり、世界レベルで活発に研究が展開されている。一方、構造相転移に関する研究も基礎的な研究であるが、将来は振動発電などの新エネルギー材料への応用として重要である。今回の研究で得られた成果は、その基礎的な機構を解明するものであり、国際的な共同研究を展開できたところに意義がある。
