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…
Negative thermal expansion and magnetoelastic coupling in the breathing pyrochlore lattice material LiGaCr4S8
G. Pokharel, A. F. May, D. S. Parker +9
The physical properties of the spinel LiGaCr4S8 have been studied with neutron diffraction, X-ray diffraction, magnetic susceptibility and heat capacity measurements. The neutron d…
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…
Unveiling the role of competing fluctuations at an unconventional quantum critical point
L. Poudel, J. M. Lawrence, L. S. Wu +7
Quantum critical points (QCPs) are widely accepted as a source of a diverse set of collective quantum phases of matter. A central question is how the order parameters of phases nea…
