Oscillatory magnetic fields for neutron resonance spin-echo spectroscopy
J. K. Jochum, A. Hecht, O. Soltwedel +6
The generation of high frequency oscillatory magnetic fields represents a fundamental component underlying the successful implementation of neutron resonant spin-echo spectrometers…
Ultra-small moment incommensurate spin density wave order masking a ferromagnetic quantum critical point in NbFe
P. G. Niklowitz, M. Hirschberger, M. Lucas +8
In the metallic magnet NbFe, the low temperature threshold of ferromagnetism can be investigated by varying the Fe excess within a narrow homogeneity range. We…
Spin-Wave and Electromagnon Dispersions in Multiferroic MnWO4 as Observed by Neutron Spectroscopy: Isotropic Heisenberg Exchange versus Anisotropic Dzyaloshinskii-Moriya Interaction
Y. Xiao, C. M. N. Kumar, S. Nandi +6
High resolution inelastic neutron scattering reveals that the elementary magnetic excitations in multiferroic MnWO4 consist of low energy dispersive electromagnons in addition to t…
Competing exchange interactions on the verge of a metal-insulator transition in the two-dimensional spiral magnet SrFeO
J. -H. Kim, Anil Jain, M. Reehuis +12
We report a neutron scattering study of the magnetic order and dynamics of the bilayer perovskite SrFeO, which exhibits a temperature-driven metal-insulator transition…
Double neutron spin resonances and gap anisotropy in underdoped superconducting NaFe0.985Co0.015As
Chenglin Zhang, Rong Yu, Yixi Su +8
We use inelastic neutron scattering to show that superconductivity in electron-underdoped NaFe0.985Co0.015As induces a dispersive sharp resonance near Er1 = 3:25 meV and a broad di…
Field Induced Magnetic Ordering and Single-ion Anisotropy in the Quasi-1D Haldane Chain Compound SrNi2V2O8: A Single Crystal investigation
A. K. Bera, B. Lake, A. T. M. N. Islam +3
Field-induced magnetic ordering in the Haldane chain compound SrNiVO and effect of anisotropy have been investigated using single crystals. Static susceptibility,…
Distinguishing and electron pairing symmetries by neutron spin resonance in superconducting NaFeCoAs
Chenglin Zhang, H. -F. Li, Yu Song +17
A determination of the superconducting (SC) electron pairing symmetry forms the basis for establishing a microscopic mechansim for superconductivity. For iron pnictide superconduct…

We use inelastic neutron scattering to study the effect of an in-plane magnetic field on the magnetic resonance in optimally doped superconductors FeSeTe (…
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$_…
