Low temperature structural effects in the (TMTSF) $_{2}$ PF $_{6}$ and AsF $_{6}$ Bechgaard salts

P. Foury-Leylekian, S. Petit, I. Mirebeau +6

We present a detailed low-temperature investigation of the statics and dynamics of the anions and methyl groups in the organic conductors (TMTSF) $_{2}$ PF $_{6}$ and (TMTSF) $_{2}$ AsF $_{6}$ (…

Understanding the magnetism in noncentrosymmetric CeIrGe3: Muon spin relaxation and neutron scattering studies

V. K. Anand, A. D. Hillier, D. T. Adroja +5

The magnetic properties of a pressure induced noncentrosymmetric heavy-fermion superconductor CeIrGe $_{3}$ have been investigated by muon spin relaxation ( $I^¼$ SR), powder neutron dif…

Crystal and magnetic structure of LaTiO3 : evidence for non-degenerate $t_{2 g}$ -orbitals

M. Cwik, T. Lorenz, J. Baier +7

The crystal and magnetic structure of LaTiO3 ~ has been studied by x-ray and neutron diffraction techniques using nearly stoichiometric samples. We find a strong structural anomaly…

Structural and magnetic aspects of the metal insulator transition in Ca $_{2 - x}$ Sr $_{x}$ RuO $_{4}$

O. Friedt, M. Braden, G. Andre +3

The phase diagram of Ca $_{2 - x}$ Sr $_{x}$ RuO $_{4}$ has been studied by neutron diffraction on powder and single-crystalline samples. The experiments reveal antiferromagnetic order and st…

First Order Transition in the Spin Dynamics of Geometrically Frustrated Yb2Ti2O7

J. A. Hodges, P. Bonville, A. Forget +10

Using neutron diffraction, 170Yb Mossbauer and muSR spectroscopies, we have examined the pyrochlore Yb2Ti2O7 where the Yb3+ S'=1/2 ground state has planar anisotropy. Below ~0.24K,…

Structural anomalies, spin transitions and charge disproportionation in LnCoO3

K. Knizek, Z. Jirak, J. Hejtmanek +2

The diamagnetic-paramagnetic and insulator-metal transitions in LnCoO3 perovskites (Ln = La, Y, rare earths) are reinterpreted and modeled as a two-level excitation process. In dis…
