▎ 摘　　要

In this study, graphene nanocrystallited carbon films were deposited with electron irradiation induced deposition in electron cyclotron resonance plasma. The orientation of nanocrstallites was revealed with transmission electron microscope (TEM) images. The TEM results showed that the graphene nanocrystallites aligned perpendicular to substrate surface. The anisotropic-magneto-resistive performances of the films were investigated under diowed that from 400 to 2 K, the film resistance varied periodically as the film rotated along its surface axial, exhibiting a sinusoidal feature. In room temperature, the average angular resolution of the film was better than 0.5%/degree, and the largest relative changing rate of the film MR ratio reached over 400% as magnetic field increased from 3 to 9 T. The mechanism of this performance was investigated through electrical transport measurement and magnetic hysteresis loops, which revealed the spin-enhanced magnetism of the nanocrystallites were the main origin of this anisotropic magnetic response behaviors.
