Abstract
The recently discovered anisotropy of the longitudinal resistance of two-dimensional electrons near half filling of high Landau levels is found to persist to much higher temperatures T when a large in-plane magnetic field B∥/T is applied. Under these conditions we find that the longitudinal resistivity scales quasilinearly with B∥/T. These observations support the notion that the onset of anisotropy at B∥=0 does not reflect the spontaneous development of charge density modulations but may instead signal an isotropic-to-nematic liquid-crystal phase transition.
