Correlated decay of triplet excitations in the Shastry-Sutherland compound SrCu(BO)
M. E. Zayed, Ch. Rüegg, Th. Strässle +8
The temperature dependence of the gapped triplet excitations (triplons) in the 2D Shastry-Sutherland quantum magnet SrCu(BO) is studied by means of inelastic neutron sc…
Measurements of thermodynamic and transport properties of EuC: a low-temperature analogue of EuO
O. Heyer, P. Link, D. Wandner +2
EuC is a ferromagnet with a Curie-temperature of K. It is semiconducting with the particularity that the resistivity drops by about 5 orders of magnitude on co…
Normal-State Hourglass Dispersion of the Spin Excitations in FeSeTe
Shiliang Li, Chenglin Zhang, Meng Wang +8
We use cold neutron spectroscopy to study the low-energy spin excitations of superconducting (SC) FeSeTe and essentially non-superconducting (NSC) FeSeTe$_…
Helimagnon Bands as Universal Spin Excitations of Chiral Magnets
M. Janoschek, F. Bernlochner, S. Dunsiger +5
MnSi is a cubic compound with small magnetic anisotropy, which stabilizes a helimagnetic spin spiral that reduces to a ferromagnetic and antiferromagnetic state in the long- and sh…
Antiferroquadrupolar Order in the Magnetic Semiconductor TmTe
J. M. Mignot, A. Gukasov, C. P. Yang +3
The physical properties of the antiferroquadrupolar state occurring in TmTe below TQ=1.8 K have been studied using neutron diffraction in applied magnetic fields. A field-induced a…
Ferromagnetic Mixed-Valence and Kondo-Lattice State in TmTe at High Pressure
P. Link, I. N. Goncharenko, J. -M. Mignot +2
Neutron diffraction experiments on TmTe at pressures up to 7 GPa are reported. The semiconductor-to-metal transition occurring at 2 GPa in this compound is accompanied by the appea…
