Abstract:Â In this communication we have investigated various cosmological consequences along with a new class of cosmological models in f(R, T) modified theory of gravity as proposed by Harko et al.(Phy. Rev. D. 024020), where the gravitational Lagrangian is replaced by an arbitrary function of Ricci scalar R and trace T of stress energy tensor. We have also studied the string cosmological models by considering the time dependent deceleration parameter with and without presence of magnetic field. In the last section of the paper the behavior of some cosmological parameters have been represented in pictorial form.
