▎ 摘　　要

We have measured magnetotransport of monolayer graphene at the minimum conductivity point in detail to study negative magnetoresistance that often appears in moderately high magnetic field. By studying several samples with different qualities, we found that negative magnetoresistance originated from potential fluctuation that leads to the residual carriers at the minimum conductivity point.
