Frustration induced dimensional reduction and coexistence of long and short-range magnetic order in NdCl
Eli Zoghlin, Matthew B. Stone, Vasile O. Garlea +3
The phenomenon of frustration greatly enriches the accessible physics of quantum magnets. With this in mind we study the magnetism of \NC using a combination of bulk properties mea…
Anisotropic magnons in a layered honeycomb ferromagnet
Travis J. Williams, Douglas L. Abernathy, Mark D. Lumsden +2
Recent experimental and theoretical studies have suggested a possible Dirac magnon gap in the two-dimensional ferromagnetic semiconductor CrSiTe. Detailed neutron scattering me…
Spin Dynamics of the Centrosymmetric Skyrmion Material GdRu2Si2
Joseph A. M. Paddison, Juba Bouaziz, Andrew F. May +6
Magnetic skyrmion crystals are traditionally associated with non-centrosymmetric crystal structures; however, it has been demonstrated that skyrmion crystals can be stabilized by c…
Codimension-Two Spiral Spin-Liquid in the Effective Honeycomb-Lattice Compound CsFeCl
Shang Gao, Chris Pasco, Otkur Omar +7
A codimension-two spiral spin-liquid is a correlated paramagnetic state with one-dimensional ground state degeneracy hosted within a three-dimensional lattice. Here, via neutron sc…
Quantum magnetism in the frustrated square lattice oxyhalides YbBi2IO4 and YbBi2ClO4
Pyeongjae Park, G. Sala, Th. Proffen +3
Square-lattice systems offer a direct route for realizing 2D quantum magnetism with frustration induced by competing interactions. In this work, the square-lattice materials YbBi2I…
Crystal Field Levels and Magnetic Anisotropy in the Kagome Compounds , , and
A. Scheie, M. Sanders, J. Krizan +4
We report the crystal field levels of several newly-discovered rare-earth kagome compounds: , , and . We…
LaCuAg: A promising host of an elastic quantum critical point
L. Poudel, C. de la Cruz, M. R. Koehler +4
Structural properties of LaCuAg have been investigated using neutron and x-ray diffraction, and resonant ultrasound spectroscopy (RUS) measurements. Diffraction measu…
Highly-anisotropic exchange interactions of iridium moments on the fcc lattice in LaIrO ( Mg, Zn)
A. A. Aczel, A. M. Cook, T. J. Williams +6
We have performed inelastic neutron scattering (INS) experiments to investigate the magnetic excitations in the weakly distorted face-centered-cubic (fcc) iridate double perovskite…
Anisotropic exchange within decoupled tetrahedra in the quantum breathing pyrochlore Ba3Yb2Zn5O11
J. G. Rau, L. S. Wu, A. F. May +9
The low energy spin excitation spectrum of the breathing pyrochlore Ba3Yb2Zn5O11 has been investigated with inelastic neutron scattering. Several nearly resolution limited modes wi…
Spin dynamics near a putative antiferromagnetic quantum critical point in Cu substituted BaFeAs and its relation to high-temperature superconductivity
M. G. Kim, M. Wang, G. S. Tucker +15
We present the results of elastic and inelastic neutron scattering measurements on non-superconducting Ba(FeCu)As, a composition close to a quan…
Magnetic structure and spin excitations in BaMn2Bi2
S. Calder, B. Saparov, H. B. Cao +4
We present a single crystal neutron scattering study of BaMn2Bi2, a recently synthesized material with the same ThCr2Si2-type structure found in several Fe-based unconventional sup…
Competing Ferri- and Antiferromagnetic Phases in Geometrically Frustrated LuFe2O4
J. de Groot, K. Marty, M. D. Lumsden +12
We present a detailed study of magnetism in LuFe2O4, combining magnetization measurements with neutron and soft x-ray diffraction. The magnetic phase diagram in the vicinity of T_N…
