スピントロニクスの形成と発展 Formation and Developments of Spintronics Research Field
History about the research of magnetoresistance effect was reviewed. Also, we looked back on the research trends in the past when both giant magnetoresistance of Fe/Cr multi layered films and large tunnel magnetoresistance at room temperature were found.<BR>Special emphasis was placed on the recent developments of huge TMR ratio for both MgO barrier tunnel junctions and Heusler alloy electrode tunnel junctions which contribute further to the development of spinelectronic research fields. Principle and importance of spin-transfer torque were also explained.
