| الوصف: | In spite of 40 years of experimental studies and several theoretical proposals, an overall interpretation of the complex behavior of the magnetoresistance (MR) of multilayer graphene, i.e. graphite, at high fields ($B \lesssim 70~$T) and in a broad temperature range is still lacking. Part of the complexity is due to the contribution of stacking faults (SFs), which most of thick enough multilayer graphene samples have. We propose a procedure that allows us to extract the SF contribution to the MR we have measured at 0.48~K $\leq T \leq$ 250~K and 0~T$\leq B \lesssim$ 65~T. We found that the MR behavior of part of the SFs is similar to that of granular superconductors with a superconducting critical temperature $T_c \sim $ 350~K, in agreement with recent publications. The measurements were done on a multilayer graphene TEM lamella, contacting the edges of the two-dimensional SFs. Comment: 8 pages, 5 figures |
