Coherent spin waves in a maximal entropy phase
Arnau Romaguera, Eugenio Paris, Elizabeth Skoropata +24
In solids, disorder is conventionally regarded as detrimental to coherence. It typically localizes and dampens collective excitations, as exemplified by Anderson localization or th…
Field-direction sensitivity of Kondo hybridization in UTe
Thomas Halloran, Gicela Saucedo Salas, Sylvia K. Lewin +6
Neutron scattering experiments on the spin-triplet superconductor UTe have established that the dominant low-energy magnetic response is along Brillouin zone boundaries, resemb…
Magnetic Field Dependence of the Spin Fluctuations in CeCuAg
X. Boraley, A. D. Christianson, J. Lass +9
Quantum phase transitions are among the most intriguing phenomena that can occur when the electronic ground state of correlated metals are tuned by external parameters such as pres…
Long-range magnetic interactions in NdPdSi and the formation of skyrmion phases in centrosymmetric metals
Viviane Peçanha-Antonio, Zhaoyang Shan, Michael Smidman +11
We present an extensive X-ray and neutron scattering study of the structure and magnetic excitations of NdPdSi, a sister compound of GdPdSi which was recently found…
Magnetic and phononic dynamics in the two-ladder quantum magnet (C5H9NH3)2CuBr4
J. Philippe, F. Elson, T. Arh +20
In quantum magnetic materials it is common to observe both static and dynamic lattice effects on the magnetic excitation spectrum. Less common is to find that the magnetic correlat…
Spin-flop-like transition as quantum critical point in CsRuO
S. D. Nabi, M. Zhu, K. Yu. Povarov +6
We report thermodynamic, neutron diffraction, and inelastic neutron scattering measurements on CsRuO, a member of the celebrated family of frustrated magnets CsMX (…
