The stability of a free boundary layer in the presence of an aligned uniform magnetic field is investigated at large values of the Reynolds number R.
The wave-number α and the phase velocity cr of the neutral disturbances are calculated as functions of the Alfvén number A and the magnetic Prandtl number γ. It is found for the case γ>O(1) that cr=0, α is independent of γ and the critical Alfvén number is 1.
