Single-shot laser-pulse-induced magnetization reversal in CoFeB/MgO-based magnetic tunnel junctions
Junta Igarashi, Sébastien Geiskopf, Takanobu Shinoda +9
We demonstrate single-shot laser-pulse-induced magnetization reversal in rare-earth-free CoFeB/MgO magnetic tunnel junctions (MTJs), a material system widely adopted in spin-transf…
Criteria to observe single-shot all-optical switching in Gd-based ferrimagnetic alloys
Wei Zhang, Julius Hohlfeld, Tian Xun Huang +6
Single-shot all-optical helicity-independent switching (AO-HIS) induced by a femto-second laser pulse has been mainly reported in Gadolinium based rare earth-transition metal (RE-T…
Influence of interlayer exchange coupling on ultrafast laser-induced magnetization reversal in ferromagnetic spin valves
Junta Igarashi, Yann Le Guen, Julius Hohlfeld +4
In this study, we explore the influence of interlayer exchange coupling on magnetization reversal triggered by femtosecond laser pulses in ferromagnetic spin valves. Our experiment…
Single laser pulse induced magnetization switching in in-plane magnetized GdCo alloys
Jun-Xiao Lin, Michel Hehn, Thomas Hauet +8
The discovery of all-optical ultra-fast deterministic magnetization switching has opened up new possibilities for manipulating magnetization in devices using femtosecond laser puls…
