Domain Wall Bianchi Type $VI_0$ Universe in $f(R,T)$ Gravity

We consider the Bianchi type-$VI_0$ space time with domain walls in the framework of the modified $f (R, T)$ theory of gravitation. To solve the field equations, we assume that the shear scalar $(\sigma)$ is proportional to the expansion scalar $(\theta)$. We also consider the parametrization of the equation of the state parameter of barotropic fluid and discuss the effect on domain walls. It has been observed that the domain wall may behave like dark energy. Some physical parameters are also discussed in detail.
