TL;DR
This paper investigates the presence of skyrmions in the fractional quantum Hall effect, showing they occur near 1/3 filling at low magnetic fields, similar to electron skyrmions near filling factor one.
Contribution
It demonstrates that skyrmions of composite fermions are relevant in the fractional quantum Hall regime at low Zeeman energies and magnetic fields.
Findings
Skyrmions are observed near 1/3 filling factor.
Relevance of skyrmions diminishes at higher magnetic fields.
Skyrmions are analogous to electron skyrmions near filling factor one.
Abstract
It is verified that, at small Zeeman energies, the charged excitations in the vicinity of 1/3 filled Landau level are skyrmions of composite fermions, analogous to the skyrmions of electrons near filling factor unity. These are found to be relevant, however, only at very low magnetic fields.
