Femtosecond signatures of optically induced magnons before ultrafast demagnetization
Reza Rouzegar, Oliver Franke, Gal Lemut +8
Optically induced demagnetization of 3d metallic ferromagnets proceeds as fast as ~100 fs and is a crucial prerequisite for spintronic applications, such as ultrafast magnetization…

Femtosecond photocurrents by the Dresselhaus bulk spin-galvanic effect in an inversion-asymmetric ferromagnet
Junwei Tong, Zdenek Kaspar, Afnan Alostaz +18
We study ultrafast photocurrents in thin films of a model ferromagnetic metal with broken bulk inversion symmetry, the half-metallic Heusler compound NiMnSb, following excitation w…
