In this paper, we consider static self-gravitating spherical space-time and determine various anisotropic solutions through the extended gravitational decoupling technique in f ( R , T , R λ ξ T λ ξ ) gravity to analyze the influence of electromagnetic field on them. We construct two different sets of modified field equations by employing the transformations on both radial as well as temporal metric potentials. The first set symbolizes the isotropic fluid distribution, thus we take Krori-Barua solution to deal with it. The indefinite second sector comprises the influence of anisotropy. In this regard, we apply some constraints to determine unknowns. Further, we observe the impact of charge as well as decoupling parameter ζ on the developed physical variables (such as energy density, radial and tangential pressures) and anisotropy. We also analyze other physical features of the compact geometry like mass, compactness and redshift along with the energy conditions. Eventually, we find that our both solutions show less stable behavior for higher values of charge near the boundary in this gravity.
