Ultrafast behavior of induced and intrinsic magnetic moments in CoFeB/Pt bilayers probed by element-specific measurements in the extreme ultraviolet spectral range
Clemens von Korff Schmising, Somnath Jana, Kelvin Yao +7
The ultrafast and element-specific response of magnetic systems containing ferromagnetic 3d transition metals and 4d/5d heavy metals is of interest both from a fundamental as well…
Using the photo-induced resonance shift in Fe and Ni as time reference for ultrafast experiments at low flux soft X-ray sources
Somnath Jana, Shreyas Muralidhar, Johan Åkerman +2
We study the optical-pump induced ultrafast transient change of the X-ray absorption at the absorption resonances of the transition metals Ni and Fe in FeNi a…
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…
LaSrVMoO: A case study for -site covalency-driven local cationic order in double perovskites
Somnath Jana, Vijay Singh, Abhishek Nag +4
An unusual atomic scale chemical fluctuation in LaSrVMoO, in terms of narrow patches of La,V and Sr,Mo-rich phases, has been probed in detail to understand the origin of such a…
Giant texturing effect in multiferroic MnWO polycrystals
Somnath Jana, Abhishek Nag, Sugata Ray
Different methods of texturing polycrystalline materials are developed over years to use/probe anisotropic material properties with relative ease, where complicated and expensive s…
Signature of an antiferromagnetic metallic ground state in heavily electron doped Sr2FeMoO6
Somnath Jana, Carlo Meneghini, Prabuddha Sanyal +4
SrFeMoO is a double perovskite compound, known for its high temperature behavior. Combining different magnetic and spectroscopic tools, we show that this compound can be…
Atomic scale chemical fluctuation in LaSrVMoO6: A proposed halfmetallic antiferromagnet
Somnath Jana, Vijay Singh, S. D. Kaushik +7
Half metallic antiferromagnets (HMAFM) have been proposed theoretically long ago but have not been realized experimentally yet. Recently, a double perovskite compound, LaSrVMoO6, h…
