Dynamical Scaling as a Signature of Multiple Phase Competition in a Frustrated Magnet
January 31, 2023
Diffuse scattering rods along {1 1 1} directions (inset) are measured at different energies and temperatures. Integrated rod intensity is scaled by temperature and plotted as a function of ħw/kBT. The data collapse onto themselves across measured temperatures and follow a scaling relation (solid line).
Scientific Achievement
The spin correlations in Yb2Ti2O7 are shown to exhibit dynamical scaling which is explained with a theory of competition between multiple phases.
Significance and Impact
These results show how multiple phase competition can broadly impact the properties of systems such as frustrated magnets which are characterized by competing ground states.
Research Details
- High resolution inelastic neutron scattering experiments were performed using BASIS on single crystals of Yb2Ti2O7 cooled to temperatures as low as 0.33 K.
- Dynamical scaling is observed experimentally and confirmed with molecular dynamics simulations.
