Carrier-tunable RKKY magnetism in a crystalline magnet
Xiang S. W. Huang, Bruno K. Saika, Satoshi Hamao +10
In itinerant magnets governed by the Ruderman-Kittel-Kasuya-Yosida (RKKY) interaction, the exchange coupling depends on both the moment-moment distance and the Fermi wavevector…

Indication of Stochastic Photothermal Dynamics around a Topological Defect in a Chiral Magnet
Dongxue Han, Asuka Nakamura, Takahiro Shimojima +4
Chiral magnets host topologically protected spin textures whose nonequilibrium dynamics are crucial in phase transitions and domain evolution, yet ultrafast defect-mediated process…

Development of precession Lorentz transmission electron microscopy
Shunsuke Hayashi, Dongxue Han, Hidenori Tsuji +2
Lorentz transmission electron microscopy (LTEM) is a powerful tool for high-resolution imaging of magnetic textures, including their dynamics under external stimuli and ultrafast n…
