  A theoretical investigation associated with obliquely propagating
ion-acoustic shock waves (IASHWs) in a three-component magnetized plasma having
inertialess non-extensive electrons, inertial warm positive and negative ions
has been performed. A Burgers equation is derived by employing the reductive
perturbation method. Our plasma model supports both positive and negative shock
structures under the consideration of non-extensive electrons. It is found that
the positive and negative shock wave potentials increase with the oblique angle
($\delta$) which arises due to the external magnetic field. It is also observed
that the magnitude of the amplitude of positive and negative shock waves is not
effected by the variation of the ion kinematic viscosity but the steepness of
the positive and negative shock waves decreases with ion kinematic viscosity.
The implications of our findings in space and laboratory plasmas are briefly
discussed.
