20.01.2022 Jairo Sinova becomes an Alexander von Humboldt Foundation Henriette Herz Scout

Jairo Sinova has become an Alexander von Humboldt Foundation Henriette Herz Scout, selected in November 2021 with another 18 scientists in Germany. JGU has been one of the most successful in this program in this round (see press release, in German). Being a AvH Scout means that Sinova can directly nominate an outstanding young scientist for a prestigious AvH Fellowship directly, without having to go through a long application process and can join the group in a relatively short (a few weeks) time.

05.06.2020 New PhD positions in SPIN+X and ElastoQmat projects

Open positions for PhD, Master and Bachelor theses and Postdoctoral positions at the Institute of Physics, Solid State Physics:

PhD Positions in Computational Topological Spintronics (SFB SPIN+X)

PhD Position in Topological Strongly Correlated Magnetic Systems (SFB ElastoQmat), Project A09

PhD Position in Topological Strongly Correlated Magnetic Systems (SFB ElastoQmat), Project B05

Our group works on the area of spintronics and nano-electronics. We work as well on other aspects of solid state theory, with a view towards multi-disciplinary approaches. Our group is very dynamic and we try to create an environment with diverse characters and expertise in order to attain a much more powerful approach to the physical challenges that we try to solve.

04.06.2020 New Science Advance publication on the prediction of the Crystal Hall effect.

Libor Smejkal has predicted a new type of phenomena in the family of spontaneous Hall effects connected to a new type of exchange splitting that depends on the momentum of the electron quasiparticle.

Abstract: Electrons, commonly moving along the applied electric field, acquire in certain magnets a dissipationless transverse velocity. This spontaneous Hall effect, found more than a century ago, has been understood in terms of the time-reversal symmetry breaking by the internal spin structure of a ferromagnetic, noncolinear antiferromagnetic, or skyrmionic form. Here, we identify previously overlooked robust Hall effect mechanism arising from collinear antiferromagnetism combined with nonmagnetic atoms at noncentrosymmetric positions. We predict a large magnitude of this crystal Hall effect in a room temperature collinear antiferromagnet RuO2 and catalog, based on symmetry rules, extensive families of material candidates. We show that the crystal Hall effect is accompanied by the possibility to control its sign by the crystal chirality. We illustrate that accounting for the full magnetization density distribution instead of the simplified spin structure sheds new light on symmetry breaking phenomena in magnets and opens an alternative avenue toward low-dissipation nanoelectronics.

01.10.2019 – Betrand Dupe leaves INSPIRE to join FNRS in Belgium

The group would like to congratulate Bertrand, who will start in October his new position at Chercheur Qualifié at the Fond National de Recherche Scientifique (FNRS) in Belgium. He will be associated with the University of Liège in the Quantum Materials (Q-mat) research unit, which is part of the Complex and Entangled Systems from Atoms to Materials department (CESAM). He will be establishing and building a group focusing on developing computational methods and researching magnetism and metals looking at skyrmion physics, transport and superconductivity.

21.01.2019 JGU Magazine publishes an article about Prof. Jairo Sinova

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.
