Description
Summary:We present theoretical results concerning some unusual properties of linear converse magnetoelectric effect (MEE) in a twisted carbon nanotube under the influence of applied magnetic field Bz. In addition to twist angle θ dependence of the zero-field paramagnetic MEE coefficient α, we found that for magnetic fields Bz exceeding deformation induced intrinsic pseudomagnetic field Bzd∝ℏθ (generated by the constant twist), α changes its sign and becomes diamagnetic. The estimates of the model parameters suggest quite an optimistic possibility to experimentally realize the discussed phenomena in twisted carbon nanotubes and graphene nanoribbons. •Linear converse magnetoelectric effect (MEE) in a twisted carbon nanotube is studied.•Twist angle dependence of zero-field paramagnetic MEE coefficient is obtained.•In applied magnetic field, MEE coefficient undergoes para-to-diamagnetic transition.
