  In the present work, using micromagnetic simulation, we show that the
magnetic coupling effect plays a very important role in the process of creation
of skyrmions in a coupled system of spin-torque nano-oscillators (STNO). First,
we have determined the magnetic ground state in an isolated STNO for different
values of perpendicular uniaxial anisotropy (PUA) and Dzyaloshinskii-Moriya
interaction (DMI). Next, we have applied a perpendicular pulse polarized
current density (J) and found that it is possible to create a metastable N\'eel
skyrmion from a disk whose ground state is a single magnetic domain. From these
results, we obtained a phase diagram of polarized current intensity vs. time of
application of the current pulse, for different values of parameters such as
PUA, DMI, and distance between the STNOs. Our results show that, depending on
the separation distance between the STNOs, the current density required to
create a skyrmion changes due to the magnetic interaction.
