  This paper is devoted to studying charged anisotropic static spherically
symmetric solutions through gravitationally decoupled minimal geometric
deformation technique in $f(R)$ gravity. For this purpose, we first consider
the known isotropic Krori-Barua solution for $f(R)$ Starobinsky model in the
interior of a charged stellar system and then include the effects of two types
of anisotropic solutions. The corresponding field equations are constructed and
the unknown constants are obtained from junction conditions. We analyze the
physical viability and stability of the resulting solutions through effective
energy density, effective radial/tangential pressure, energy conditions, and
causality condition. It is found that both solutions satisfy the stability
range as well as other physical conditions for specific values of charge as
well as model parameter and anisotropic constant. We conclude that the modified
theory under the influence of charge yields more stable behavior of the
self-gravitating system.
