Element resolved evidence of superdiffusive terahertz spin current arising from ultrafast demagnetization process
R. Gupta, F. Cosco, R. S. Malik +13
Using element-specific measurements of the ultrafast demagnetization of Ru/FeCo heterostructures, we show that Ru can exhibit a significant magnetic contrast (3% asym…
Experimental confirmation of the delayed Ni demagnetization in FeNi alloy
Somnath Jana, Ronny Knut, Shreyas Muralidhar +6
Element-selective techniques are central for the understanding of ultrafast spin dynamics in multi-element materials like magnetic alloys. Recently, though, it turned out that the…
Ultrafast magnetization dynamics in half-metallic CoFeAl Heusler alloy
R. S. Malik, E. K. Delczeg-Czirjak, D. Thonig +12
We report on optically induced, ultrafast magnetization dynamics in the Heusler alloy , probed by time-resolved magneto-optical Kerr effect. Experimental resul…
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…
Exchange dependent ultrafast magnetization dynamics in FeNi alloys
Somnath Jana, Ronny Knut, Erna K. Delczeg-Czirjak +13
Element specific ultrafast demagnetization was studied in FeNi alloys, covering the concentration range between . For all compositions, we observe a delay…
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…
