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…
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.…
Single-laser pulse toggle switching in CoHo and CoDy single layer alloys : when domain wall motion matters
B. Kunyangyuen, G. Malinowski, D. Lacour +7
Single pulse All Optical Helicity-Independent Toggle Switching is observed in CoHo and CoDy alloys single layers. An original reversal mechanism is reported which contrasts with th…
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…
