Observations of highly ionized species (O VI, C IV, N V, Si IV ) in the interstellar medium (ISM) indicate the existence of substantial amounts of plasma at Temperatures of T ˜ 105. To explain the line ratios observed, it has been proposed to be the result of mixing by turbulence at the interfaces between hot (T ˜ 106) and warm (T ˜ 104) media. In addition, the the ISM is magnetized. And the magnetic field is expected to be a controlling factor that can suppress the instabilities that lead to the onset of turbulence at such interfaces. We present results of numerical simulations of turbulent mixing layers, using a MHD code with radiative cooling. With a more complete exploration of parameter space, this work will provide more reliable diagnostics of turbulent mixing layers than those available today.
