| Summary:
Recent years have witnessed an enormous rise in research interest in magnetic
skyrmions owing to their capability to improve over contemporary spintronic
devices. An overview of the various magnetic interactions responsible for the
formation of skyrmion together with distinct noncentrosymmetric and
centrosymmetric skyrmion candidates is given in this review article. The
magnetic interactions known as Dzyaloshinskii-Moriya interactions (DMI) have
been extensively studied over the years to better understand the mechanism of
skyrmions in chiral magnets that have larger skyrmion sizes. Because of their
low skyrmion size, the centrosymmetric frustrated magnets are dwelling to
skyrmions controlled by long-range interactions such as the
Ruderman-Kittel-Kasuya-Yosida interaction (RKKY), which may be useful in the
development of high-density memory devices. To lay a solid foundation for the
magnetic interactions involved in skyrmion formations and many other special
physical properties, more research in the field of centrosymmetric skyrmions is
required. Apart from studying candidates with low skyrmion sizes, one of the
main goals for the future is to better understand the dynamics of skyrmion
using polarized magnons, which has the potential to be extremely beneficial for
spintronic applications.
