A. Villares Ferrer, R.L. Doretto, and A.O. Caldeira
TL;DR
This paper explains the non-monotonic NMR linewidth behavior in 2D quantum Hall systems by examining how skyrmion localization and dynamics, influenced by disorder and temperature, affect the system's magnetic properties.
Contribution
It introduces a new understanding of how skyrmion localization and temperature-dependent dynamics influence NMR linewidths in quantum Hall ferromagnets.
Findings
NMR linewidth exhibits non-monotonic behavior due to skyrmion effects.
Disorder-induced skyrmion localization impacts magnetic resonance signals.
Temperature affects skyrmion mobility, altering NMR linewidths.
Abstract
The non-monotonic behavior of the NMR signal linewidth in the 2D quantum Hall system is explained in terms of the interplay between skyrmions localization, due to the influence of disorder, and the non-trivial temperature dependent skyrmion dynamics.
