      Divalent EuRh2Si2 as a Reference for the Luttinger Theorem and Antiferromagnetism in Trivalent Heavy-Fermion YbRh2Si2 

      Güttler, M.; Generalov, A.; Fujimori, S. I.; Kummer, K.; Chikina, A.; Seiro, Silvia; Danzenbächer, S.; Koroteev, Yury M.; Chulkov, Evgueni V.; Radovic, M.; Shi, M.; Plumb, Nicholas C.; Laubschat, C.; Allen, J. W.; Krellner, Cornelius; Geibel, Christoph; Vyalikh, D. V. (Nature Publishing Group, 2019-02-15)
      Application of the Luttinger theorem to the Kondo lattice YbRh2Si2 suggests that its large 4f derived Fermi surface (FS) in the paramagnetic (PM) regime should be similar in shape and volume to that of the divalent ...

      Emerging 2D-ferromagnetism and strong spin-orbit coupling at the surface of valence-fluctuating EuIr2Si2 

      Schulz, Susanne; Nechaev, Ilya A.; Guettler, Monika; Poelchen, Georg; Generalov, Alexander; Danzenbaecher, Steffen; Chikina, Alla; Seiro, Silvia; Kliemt, Kristin; Vyazovskaya, Alexandra Yu; Kim, Timur K.; Dudin, Pavel; Chulkov, Evgueni V.; Laubschat, Clemens; Krasovskii, Eugene E.; Geibel, Christoph; Krellner, Cornelius; Kummer, Kurt; Vyalikh, Denis V. (Nature Publishing Group, 2019-06-03)
      The development of materials that are non-magnetic in the bulk but exhibit two-dimensional (2D) magnetism at the surface is at the core of spintronics applications. Here, we present the valence-fluctuating material EuIr2Si2, ...
