Abstract :
In the present paper, we have investigated magnetized LRS Bianchi type-I massive string cosmological model for perfect fluid distribution with cosmological termΛ. To obtain the explicit solution of the model we suppose expansion θ is propotional to the shear σ and Λ is inversely proportional to R^3, where R is scale factor under two cases: (i) ρ+λ=0 and (ii) ρ-λ=0 where ρ and λ are proper energy density and string tension density respectively. We have also discussed physical and geometrical characteristics of the cosmological model.
