摘要：

Charge transfer by radial Hall current in varying magnetic flux in Corbino geometry under QHE conditions has been investigated. Having measured the quantity of this charge we have determined conductivity sigma-xy at filling factors close to integer. Accuracy of quantization in plateau region proves to be unexpectedly low.
