  The mixed spin-1/2 Ising model and spin-1 Blume-Capel model in an hexagonal
nanowire structure under the presence of crystal field is considered. The free
energy is obtained through the transfer matrix technique, which is solved
numerically. Our main result lies in the presence of pseudo-transition in low
temperature region near the ferrimagnetic/ferromagnetic boundary, due to the
influence of a crystal field. The evidence of a pseudo-transition is observed
in several quantities. Free energy first derivative quantities like entropy and
internal energy show an abrupt but continuous jump, whereas quantities
associated with second derivatives of the free energy like the specific heat
exhibit a strong sharp peak, quite similar to a second order phase transition.
We also investigate magnetization patterns and do not find evidence of
spontaneous magnetization. Nevertheless, assuming a small magnetic field, we
can induce a magnetization which resembles a spontaneous magnetization at a
pseudo-critical temperature.
