N. Büttgen,Joachim Hemberger,Veronika Fritsch,A. Krimmel,M Mücksch,H-A Krug von Nidda,Peter Lunkenheimer,R. Fichtl,Vladimir Tsurkan,Vladimir Tsurkan,Alois Loidl +10 more
TL;DR: In this article, a long-range orbital ordering in polycrystalline (PC) FeCr2S4, and a glassy freezing of the orbital degrees of freedom in single crystals (SCs) were investigated.

High-field NMR of the quasi-one-dimensional antiferromagnet LiCuVO 4
TL;DR: In this paper, the quasi-one-dimensional (1D) antiferromagnetic LiCuVO$_4$ in magnetic fields up to 30 T was studied, where the magnetic moments are aligned parallel to the applied field and their values alternate sinusoidally along the magnetic chains.

Intermediate-valence behavior of the transition-metal oxide CaCu 3 Ru 4 O 12
A. Krimmel,Armin Günther,W. Kraetschmer,H. Dekinger,N. Büttgen,Volker Eyert,Alois Loidl,Denis Sheptyakov,Ernst-Wilhelm Scheidt,Wolfgang Scherer +9 more
TL;DR: In this article, the transition metal oxide (Ru) with perovskite-type structure showed characteristic properties of an intermediate-valence system and the temperature-dependent susceptibility exhibits a broad maximum around 150-160 K. At this temperature, neutron powder diffraction reveals a small but significant volume change whereby the crystal structure is preserved.
