Glassy Spin Freezing and Gapless Spin Dynamics in a Spatially Anisotropic Triangular Antiferromagnet Ag2MnO2

S. Ji, J. -H. Kim, Y. Qiu +6

Using elastic and inelastic neutron scattering techniques, we show that upon cooling a spatially anisotropic triangular antiferromagnet Ag $_{2}$ MnO $_{2}$ freezes below $T_{f} \sim 50$ K…

Spin Gap and Resonance at the Nesting Wavevector in Superconducting FeSe0.4Te0.6

Yiming Qiu, Wei Bao, Yang Zhao +9

Neutron scattering is used to probe magnetic excitations in FeSe_{0.4}Te_{0.6} (T_c=14 K). Low energy spin fluctuations are found with a characteristic wave vector $(0.5, 0.5, L)$ th…
