Engineering ultrafast spin currents and terahertz transients by magnetic heterostructures
T. Kampfrath, M. Battiato, P. Maldonado +9
In spin-based electronics, information is encoded by the spin state of electron bunches. Processing this information requires the controlled transport of spin angular momentum thro…
Electric breakdown in ultra-thin MgO tunnel barrier junctions for spin-transfer torque switching
M. Schäfers, V. Drewello, G. Reiss +6
Magnetic tunnel junctions for spin-transfer torque switching were prepared to investigate the dielectric breakdown. The breakdown occurs typically at voltages not much higher than…
Direct imaging of the structural change generated by dielectric breakdown in MgO based magnetic tunnel junctions
A. Thomas, V. Drewello, M. Schaefers +6
MgO based magnetic tunnel junctions are prepared to investigate the dielectric breakdown of the tunnel barrier. The breakdown is directly visualized by transmission electron micros…
Magnetization dynamics in optically excited nanostructured nickel films
Georg M. Müller, Gerrit Eilers, Zhao Wang +4
In this work, Laser-induced magnetization dynamics of nanostructured nickel films is investigated. The influence of the nanosize is discussed considering the time-scale of hundreds…
Unusual spin-wave population in nickel after femtosecond laser pulse excitation
Benjamin Lenk, Gerrit Eilers, Jaroslav Hamrle +1
The spin-wave relaxation mechanisms after intense laser excitation in ferromagnetic nickel films are investigated with all-optical pump-probe experiments. Uniform precession (Kitte…
