A publication by the Organic Spintronics Team (OST) has been published in the Journal of Physical Chemistry C.
This paper presents an application of the recently developed technique for predictions of spin-admixture in molecules. As a computationally robust and efficient, "high-throughput" technique, it is used to describe general trends of in the spin admixture of several classes of molecules, from complex single-molecule magnets to organic polymers. The results emphasize the often counterintuitive variations of molecular spin-orbit coupling with molecular chemical composition and structure.
This paper presents an investigation of ultrafast dynamics in antiferromagnets which is a part of a developing field of an Antiferromagnetic spintronics.By performing magneto-optical pump-probe experiments we excite coherent longitudinal oscillations of the antiferromagnetic order parameter that cannot be described by a thermodynamic Landau-Lifshitz approach. We interpret these oscillations as manifestation of an entanglement of pairs of magnons generated by femtosecond optical pulses. The results open a way to creation and manipulation of quantum entanglement in antiferromagnetic systems at macroscopic scales.
A joint publication by the Organic Spintronics Team (OST) and collaborators from the ERC Synergy Project, the Max-Planck Institute for Polymer Research in Mainz and the University in Mons (Belgium) has been published in Nature Physics.
This paper presents a novel experimental perspective on spin and charge dynamics in high-mobility polymers, supported by calculations of the spin admixture distribution in realistic, large-scale polymer morphology models performed by the OST.
A joint publication by the Organic Spintronics Team and other ERC Synergy Project collaborators has been published in Nature Electronics. This paper presents experimental measurements of extremely long spin diffusion lengths in high-mobility organic polymer materials.
Modeling by the Organic Spintronics Team explains this finding in terms of the weak up-down spin mixing found in planar conjugated polymers with weak spin-orbit coupling.
The "JGU Magazine" publishes an article about Prof. Jairo Sinova in which readers get an insight of Jairos scientific career, the research field of spintronics and his love for Mainz. Further he talks about the Spin Phenomena Interdisciplinary Center (SPICE) and the Interdisciplinary Spintronics Research Group (INSPIRE) which he built up and leads at the Institute for Physics at the Johannes Gutenberg University in Mainz.
