Abstract:
By introducing a strain rate $\dot {\epsilon}$
generated pseudo-electric field $E^d_x\propto \hbar \dot
{\epsilon}$, 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. The estimates
of the model parameters suggest quite an optimistic possibility to
experimentally realize the predicted phenomena in plastically
deformed graphene.
