Abstract

We study the magnetoresistance (MR) of a multiwalled carbon nanotube (MWNT) as a function of the angle (θtilt) between the external field (Bext) and the MWNT axis. With Bext oriented along the nanotube axis, its MR exhibits two symmetric (with respect to zero field) sharp minima that shift to higher Bext as this field is rotated away from the axis. We suggest that these minima are associated with a cancellation of the nanotube effective flux as predicted by Nakanishi and Ando [J. Phys. Soc. Jpn. 74, 3027 (2005)].
