Synthesis of CMR manganites and ordering phenomena in complex transition metal oxides
… x-ray scattering in the investigation of complex ordering phenomena in La7/8Sr1/8MnO3 and La1Sr2Mn2O7 at the transition metal LII, III-edges and the rare earth MIV, V-edges. Two new devices have been developed: one is the rotating specimen holder for laboratory x-ray powder diffraction, which not …

Interplay between charge, spin and orbital ordering in La 1 - Kappa Sr Kappa MnO 3 manganites
… work interplay between charge, orbital and spin ordering in lightly doped La1-xSrxMnO3 with x~1/8 has been studied using both resonant and non-resonant (high-energy) X-ray scattering (at Advance Photon Source at Argonne National Laboratory and HASY Lab at DESY) as well as neutron scattering …

Thermal expansion and magnetostriction studies on iron pnictides
… has a very pronounced anomaly associated with Pr-ordering exhibits a large magnetostriction at low temperatures. By discussing this effect along with the magnetization, resistivity and other measurements, it is found that this large magneto-elastic effect may originate from the correlations …

Ladungs- und Orbitalordnungsphänomene in Übergangsmetalloxidverbindungen unter hydrostatischem Druck
… reflections corresponding to the order phenomena under pressure using scattering of high-energy synchrotron radiation. The maximum pressure that can be reached is 1.25 GPa. Until today there has been no possibility to conduct such studies of charge and orbital order superlattice …

Einfluß der magnetischen Ordnung auf Supraleitung und Kristallstruktur in Seltenerd-Nickel-Borkarbid-Verbindungen
… experimental studies on the interplay of both ordering phenomena. Neutron diffraction is used to determine the magnetic order and the resulting changes of the crystal structure. Experiments are performed on polycrystalline and single crystal samples in dependence on temperature and external …
