Fermi Level Controlled Ultrafast Demagnetization Mechanism in Half-Metallic Heusler Alloy
Santanu Pan, Takeshi Seki, Koki Takanashi +1
The electronic band structure-controlled ultrafast demagnetization mechanism in Co2FexMn1-xSi Heusler alloy is underpinned by systematic variation of composition. We find the spin-…

Edge localization of spin waves in antidot multilayers with perpendicular magnetic anisotropy
S. Pan, S. Mondal, M. Zelent +5
We study the spin-wave dynamics in nanoscale antidot lattices based on Co/Pd multilayers with perpendicular magnetic anisotropy. Using time-resolved magneto-optical Kerr effect mea…

Controlled co-excitation of direct and indirect ultrafast demagnetization in Co/Pd multilayer with large perpendicular magnetic anisotropy
Santanu Pan, Olav Hellwig, Anjan Barman
Ever since its discovery in 1996, ultrafast demagnetization has ignited immense research interest due to its scientific rigor and technological potential. A flurry of recent theore…
