Outline of Final Research Achievements

In rare earth iron garnets, magnetic moments of rare earth ions and iron ones couple antiferromagnetically. Since the g-factors of rare earth ions and iron ones are different, there exists two compensation temperatures, i.e., magnetic compensation temperature (TM) and angular momentum compensation temperature (TA). Although TM is observed by the magnetization measurement, there was no direct method to measure TA. We have developed the mechanically rotational machine to measure TA. By using this, both TM and TA in (Ho, Dy)3Fe5O12 have been determined. Since the magnetization dynamics becomes high near TA, this method is expected to contribute to spintronics.

Academic Significance and Societal Importance of the Research Achievements

スピントロニクスの重要な材料である希土類鉄ガーネットは、フェリ磁性体であり、一般に磁気補償温度(TM)と角運動量補償温度(TA)が違っている。角運動量補償温度(TA)近傍では、磁化の運動が早くなることから、スピントロニクスへの様々な応用が期待されるが、これまではTAを直接に測定する方法がなかった。今回我々は、力学回転装置を開発し、バーネット効果を用いてTAを直接検する方法を得た。これを用いて、(Ho,Dy )3Fe 5O12のTAとTMの関係を明らかにした。
