摘要：
Temperature dependence of the diagonal resistivity rho(xx) was measured at v = 1 quantum Hall regime as a function of the total magnetic field. As a result of activation type fitting, we found that the high-temperature extrapolated value of the diagonal resistivity rho(0) depends on the total magnetic field. We discuss the temperature dependence of rho(0) in terms of skyrmion excitation using the Landauer-Buttiker-type edge channel model including the back-scattering. (C) 1998 Elsevier Science B.V.
