Single-Pulse Optical Switching combined with Current-Induced Motion of Skyrmionic Spin Textures
Edoardo Mangini, Duc Minh Tran, Boonthum Kunyangyuen +5
Magnetic skyrmions are promising nanoscale information carriers because their position can be manipulated by electrical currents. The additional ability of deterministic control of…
Laser induced ultrafast Co 3d and Ho 4f spin dynamics in CoHo ferrimagnetic alloys
Deeksha Gupta, Boonthum Kunyangyuen, Matthias Riepp +8
The transition metal (TM) / rare-earth (RE) alloys have received renewed interest lately as model systems to decipher the origin of all-optical helicity-independent switching (AO-H…
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…
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…
