This paper is devoted to application of fractional multistep method in the numerical solution of fractional diffusion-wave equation. By transforming the diffusion-wave equation into an equivalent integro-differential equation and applying Lubich's fractional multistep method of second order we obtain a scheme of order O(tau(alpha) + h(2)) for 1 <= alpha <= 1.71832 where a is the order of temporal derivative and tau and h denote temporal and spatial stepsizes. The solvability, convergence and stability properties of the algorithm are investigated and numerical experiment is carried out to verify the feasibility of the scheme.
