Observation of pinning mode of stripe phases of 2D systems in high Landau levels
arXiv:0803.3228 · doi:10.1103/PhysRevLett.100.256801
Abstract
We study the radio-frequency diagonal conductivities of the anisotropic stripe phases of higher Landau levels near half integer fillings. In the hard direction, in which larger dc resistivity occurs, the spectrum exhibits a striking resonance, while in the orthogonal, easy direction, no resonance is discernable. The resonance is interpreted as a pinning mode of the stripe phase.
