▎ 摘　　要

Graphene micro-Hall probes were developed for a scanning Hall probe microscope system and used for the direct magnetic imaging domains of demagnetized NdFeB permanent magnet for the first time. The Hall coefficient and minimum magnetic field resolution of graphene Hall probes at 1 kHz were found to be 0.18 Omega/G and 0.20 G/root Hz for a drive current of 3 mu A at room temperature in vacuum. The magnetic domains in NdFeB demagnetized magnet were observed at 300K, 126K and 3K successfully. (C) 2014 Elsevier B.V. All rights reserved.
