Magnetic excitation spectrum and hierarchy of magnetic interactions in ErFeO3
Dnyaneshwar R. Bhosale, Piotr Fabrykiewicz, Devashibhai Adroja +3
We report a comprehensive investigation of the excitation spectrum of ErFeO orthoferrite by means of time-of-flight neutron spectroscopy. The spectrum consists of two distinct…
Field-Tuned Quantum Effects in a Triangular-Lattice Ising Magnet
Yayuan Qin, Yao Shen, Changle Liu +19
We report thermodynamic and neutron scattering measurements of the triangular-lattice quantum Ising magnet TmMgGaO 4 in longitudinal magnetic fields. Our experiments reveal a quasi…
Neutron Spin Resonance in the Heavily Hole-doped KFeAs Superconductor
Shoudong Shen, Xiaowen Zhang, Hongliang Wo +6
We report high-resolution neutron scattering measurements of the low energy spin fluctuations of KFeAs, the end member of the hole-doped BaKFeAs fam…
Putative spin-nematic phase in BaCdVO(PO)
M. Skoulatos, F. Rucker, G. J. Nilsen +14
We report neutron scattering and AC magnetic susceptibility measurements of the 2D spin-1/2 frustrated magnet BaCdVO(PO). At temperatures well below $T_{\sf N}\approx 1…
Interplay of electronic and spin degrees in ferromagnetic SrRuO: anomalous softening of magnon gap and stiffness
Kevin Jenni, Stefan Kunkemöller, Daniel Brüning +7
The magnon dispersion of ferromagnetic SrRuO was studied by inelastic neutron scattering experiments on single crystals as function of temperature. Even at low temperature the…
Pseudo-Goldstone magnons in the frustrated S=3/2 Heisenberg helimagnet ZnCr2Se4 with a pyrochlore magnetic sublattice
Y. V. Tymoshenko, Y. A. Onykiienko, T. Mueller +13
Low-energy spin excitations in any long-range ordered magnetic system in the absence of magnetocrystalline anisotropy are gapless Goldstone modes emanating from the ordering wave v…
Spin Resonance and Magnetic Order in an Unconventional Superconductor
D. G. Mazzone, S. Raymond, J. L. Gavilano +4
Unconventional superconductivity in many materials is believed to be mediated by magnetic fluctuations. It is an open question how magnetic order can emerge from a superconducting…
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…
Robust Upward Dispersion of the Neutron Spin Resonance in the Heavy Fermion Superconductor CeYbCoIn
Yu Song, John Van Dyke, I. K. Lum +10
The neutron spin resonance is a collective magnetic excitation that appears in copper oxide, iron pnictide, and heavy fermion unconventional superconductors. Although the resonance…
Magnon spectrum of the helimagnetic insulator Cu2OSeO3
P. Y. Portnichenko, J. Romhanyi, Y. A. Onykiienko +11
Complex low-temperature ordered states in chiral magnets are typically governed by a competition between multiple magnetic interactions. The chiral-lattice multiferroic Cu2OSeO3 be…
Spin reorientation in Na-doped BaFeAs studied by neutron diffraction
F. Wasser, A. Schneidewind, Y. Sidis +4
We have studied the magnetic ordering in Na doped BaFeAs by unpolarized and polarized neutron diffraction using single crystals. Unlike previously studied FeAs-based compou…
Normal-State Spin Dynamics and Temperature-Dependent Spin Resonance Energy in an Optimally Doped Iron Arsenide Superconductor
D. S. Inosov, J. T. Park, P. Bourges +8
The proximity of superconductivity and antiferromagnetism in the phase diagram of iron arsenides, the apparently weak electron-phonon coupling and the "resonance peak" in the super…
