Pinning mode resonance of a Skyrme crystal near Landau level filling factor $\nu$=1

Abstract

Microwave pinning-mode resonances found around integer quantum Hall effects, are a signature of crystallized quasiparticles or holes. Application of in-plane magnetic field to these crystals, increasing the Zeeman energy, has negligible effect on the resonances just below Landau level filling $\nu =2$, but increases the pinning frequencies near $\nu =1$, particularly for smaller quasiparticle/hole densities. The charge dynamics near $\nu =1$, characteristic of a crystal order, are affected by spin, in a manner consistent with a Skyrme crystal.
