Single-shot laser-pulse-induced magnetization reversal in CoFeB/MgO-based magnetic tunnel junctions
Junta Igarashi, Sébastien Geiskopf, Takanobu Shinoda +9
The paper demonstrates that a single laser pulse can reverse the magnetization in CoFeB/MgO magnetic tunnel junctions by adjusting the Ru capping layer thickness, and observes the…
Type-II-like ultrafast demagnetization behavior in NiCo2O4 thin films
Ryunosuke Takahashi, Kaede Yamada, Harjinder Singh +10
Rare-earth-ferrimagnetic oxides are emerging as attractive platforms for investigating ultrafast spin dynamics. Here, we study the photoinduced magnetization dynamics of epitaxial…
Ultrafast Spin Accumulations Drive Magnetization Reversal in Multilayers
Harjinder Singh, Alberto Anadón, Junta Igarashi +5
Engineering and controlling heat and spin transport on the femtosecond time-scale in spintronic devices opens up new ways to manipulate magnetization with unprecedented speed. Yet…
Single-Shot Magnetization Reversal in Ferromagnetic Spin Valves Enabled via Heat Control
Kazuaki Ishibashi, Junta Igarashi, Alberto Anadón +7
We study laser induced ultrafast magnetization reversal in a ferromagnetic spin valve by comparing the effects of direct laser excitation and ultrashort hot electron pulses. A wedg…
Single-shot all-optical magnetization switching in in-plane magnetized magnetic tunnel junction
S. Geiskopf, J. Igarashi, G. Malinowski +6
Single pulse All Optical Helicity-Independent Switching is demonstrated in an in-plane magnetized magnetic tunnel junction. A toggle switching of the 2nm thick Co40Fe40B20 soft lay…
