Accelerating the laser-induced demagnetization of a ferromagnetic film by antiferromagnetic order in an adjacent layer
Ivar Kumberg, Evangelos Golias, Niko Pontius +8
We study the ultrafast demagnetization of Ni/NiMn and Co/NiMn ferromagnetic/antiferromagnetic bilayer systems after excitation by a laser pulse. We probe the ferromagnetic order of…
Ultrafast optically induced ferromagnetic state in an elemental antiferromagnet
E. Golias, I. Kumberg, I. Gelen +9
We present evidence for an ultrafast optically induced ferromagnetic alignment of antiferromagnetic Mn in Co/Mn multilayers. We observe the transient ferromagnetic signal at the ar…
Electronic structure studies on single crystalline Nd2PdSi3, an exotic Nd-based intermetallic: Evidence for Nd 4f hybridization
Kalobaran Maiti, Tathamay Basu, Sangeeta Thakur +6
In the series R2PdSi3, Nd2PdSi3 is an anomalous compound in the sense that it exhibits ferromagnetic order unlike other members in this family. The magnetic ordering temperature is…
Local excitons in silicon induced by SiGe quantum huts
Arka Bikash Dey, Milan K Sanyal, Swapnil Patil +4
Conversion of Si to a direct bandgap semiconductor for optoelectronic application is a great challenge for many decades. It is proposed that embedment of suitable sized quantum dot…
