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…
Exploring Co, Fe, and Ni Reference Layers for Single-Pulse All-Optical Reversal in Ferromagnetic Spin Valves
Jun-Xiao Lin, Yann Le Guen, Julius Hohlfeld +6
We investigate the magnetization reversal process induced by a single femtosecond laser pulse in ferromagnetic spin valves by systematically comparing reference layers composed of…
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…
Controlling Single-Pulse Magnetization Switching through Angular Momentum Reservoir Engineering
B. Kunyangyuen, G. Malinowski, D. Lacour +6
We report a systematic study of single pulse all optical helicity independent switching in CoGd bilayers, revealing that the magnetization reversal dynamics can be tuned over more…
Role of Heat Transport in All-Optical Helicity-Independent Magnetization Switching
V. Raposo, J. Hohlfeld, S. Mangin +1
Single-shot all-optical helicity independent switching processes are investigated using advanced micromagnetic modeling in a ferrimagnetic thin film embedded in a multilayer stack.…
