Analysis of the linear relationship between asymmetry and magnetic moment at the M-edge of 3d transition metals
Somnath Jana, R. S. Malik, Yaroslav O. Kvashnin +11
The magneto-optical response of Fe and Ni during ultrafast demagnetization is studied experimentally and theoretically. We have performed pump-probe experiments in the transverse m…

Inhomogeneous magnon scattering during ultrafast demagnetization
R. Knut, E. K. Delczeg-Czirjak, S. Jana +20
NiFe (Py) and Py alloyed with Cu exhibit intriguing ultrafast demagnetization behavior, where the Ni magnetic moment shows a delayed response relative to the Fe, an…
