In the magnetic gradient region, successive up-down magnetization is generated by the spin-orbit torque and, in turn, injected into the magnetic wire with a strong perpendicular magnetic anisotropy, resulting in multiple domain propagation. We found that the threshold current for the multiple domain injection is minimized when an effective magnetic anisotropy at the end becomes nearly zero. As the effective anisotropy becomes more negative, the threshold current increases with a magnetic anisotropy gradient because the gradient acts as a barrier to the domain injection. Our result provides design rules for the optimized magnetic anisotropy gradient for the multiple domain generation and injection.","PeriodicalId":42623,"journal":{"name":"Journal of the Korean Magnetics Society","volume":" ","pages":""},"PeriodicalIF":0.2,"publicationDate":"2021-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49167460","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although the pump-probe magneto-optical Kerr effect (MOKE) instrument is most widely used in Femtomagnetism to measure reflectivity and Kerr responses, it is considerably hard to analyze fundamental interactions of electron-spin or lattice-spin due to the complex nature of the reflectivity. The ultrafast Sagnac interferometer has the great advantage of obtaining the real and imaginary parts of MOKE as well as the reflectivity and the lattice displacement at the same time. Therefore, through the rigorous investigation of temporal sequences of electron, lattice, and spin systems, we expect this instrument to play an leading role in unraveling interaction mechanisms between systems.","PeriodicalId":42623,"journal":{"name":"Journal of the Korean Magnetics Society","volume":" ","pages":""},"PeriodicalIF":0.2,"publicationDate":"2021-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42842104","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
