Thin films of undoped amorphous carbon thin film were fabricated by using Chemical Vapor Deposition and their structure was investigated by using High Resolution Transmission Electron Microscopy and Raman Spectroscopy. Angular magnetoresistance (MR) has been observed for the first time in these undoped amorphous carbon thin films in temperature range of 2 similar to 40 K. The maximum magnitude of angular MR was in the range of 9.5% similar to 1.5% in 2 similar to 40 K. The origin of this angular MR was also discussed.
