Analog of Fishtail Anomaly in Plastically Deformed Graphene    [PDF]

S. Sergeenkov, F. M. Araujo-Moreira
By introducing a strain rate generated pseudo-electric field, we discuss a magnetic response of a plastically deformed graphene. Our results demonstrate the appearance of dislocation induced paramagnetic moment in a zero applied magnetic field. More interestingly, it is shown that in the presence of the magnetoplastic effect, the resulting magnetization exhibits typical features of the so-called fishtail anomaly (previously observed in superconductors). The estimates of the model parameters suggest quite an optimistic possibility to experimentally realize the predicted phenomena in plastically deformed graphene.
