Emergent Dispersive Multipolar Excitations in NaErSe
Zheng Zhang, Mingfang Shu, Mingtai Xie +6
In most condensed-matter systems, local and collective excitations remain decoupled due to their distinct energy scales. Here, we identify coupled local-collective excitations in t…
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…
Intermediate Field Spin(on) Dynamics in -RuCl
C. L. Sarkis, K. D. Dixit, P. Rao +11
We present comprehensive inelastic neutron spectroscopic maps of the magnetic field-induced disordered phase of the Kitaev quantum spin liquid candidate material -RuCl. For…
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…
From continuum excitations to sharp magnons via transverse magnetic field in the spin-1/2 Ising-like triangular lattice antiferromagnet Na2BaCo(PO4)2
Leonie Woodland, Ryutaro Okuma, J. Ross Stewart +2
We report high-resolution inelastic neutron scattering measurements of the excitation spectrum in large single crystals of the spin-1/2 triangular lattice Ising-like antiferromagne…
Magnetic excitations in biaxial-strain detwinned -RuCl
Yi Li, Yanyan Shangguan, Xinzhe Wang +10
The honeycomb magnet -RuCl has been a leading candidate for realizing the Kitaev quantum spin liquid (QSL), but its intrinsic spin dynamics have remained obscured by crys…
