  Controlled creation of stable chiral spin textures is required to use them as
an energy-efficient information carrier in spintronics. Here we have studied
the stable creation of isolated chiral spin texture (skyrmion and antiskyrmion)
and its pair through the magnetization reversal of a rectangular nanostructure
using spin-polarized currents. An isolated spin texture is created through a
negative current pulse. Dynamics of the stable spin texture are explored under
external magnetic fields, and the resonant frequencies are calculated. A stable
skyrmion pair is created using an asymmetric current pulse, and their
interaction is studied using the Thiele equation. The stability of isolated or
paired spin texture depends on the DMI strength, spin-polarized current
density, and pulse duration. In addition, the stability of the skyrmion pair
depends on their initial separation, and a threshold for the separation between
skyrmions of 78 nm is observed.
