Recent Topics of Magnetic Domain Observation Technique of Nano-scaled Magnetic Materials Reviewed

Takezawa Masaaki

IEEJ Transactions on Fundamentals and Materials ( The Institute of Electrical Engineers of Japan ) 141 ( 2 ) 112 - 117 2021.02

Authorship：Lead author Language：English Publishing type：Research paper (scientific journal)

<p>Recent topics of magnetic domain observation technique of nano-scaled magnetic materials were summarized and reported. Magnetic properties of nano-scaled magnetic materials are highly dependent on the magnetic domain structure inside their magnetic materials. Therefore, an observation technique of the magnetic domain structure of magnetic materials is an extremely important field of technology to improve the performance of various devices. Spatial resolution of the domain observation and the observation technique in high magnetic fields were described.</p>

Influence of Oxygen or Carbon Impurities on Domain Structure of Sm-Co Magnets Reviewed

Takezawa Masaaki, Sakakura Kenji, Tanaka Jun, Machida Hiroaki, Fujiwara Teruhiko

IEEJ Transactions on Fundamentals and Materials ( The Institute of Electrical Engineers of Japan ) 141 ( 2 ) 133 - 138 2021.02

Authorship：Lead author Language：English Publishing type：Research paper (scientific journal)

<p>Magnetic domain structure changes during a demagnetization process of 2-17 type Sm-Co magnets with different amounts of carbon and oxygen were observed using a Kerr effect microscope. Moreover, the effects of the excess carbon and excess oxygen compositions on the demagnetization process of the magnets were investigated. As a result, it is found that in the Sm-Co magnets with high carbon and oxygen composition, the nucleation of reversal magnetic domains inside grains during the demagnetization process easily occurs at a lower demagnetization field strength. The nucleation of the reversal magnetic domain in grains causes a decrease in a squareness ratio of a demagnetization curve.</p>
