In this paper we present stability results concerning the inverse problem of determining two time independent coefficients for a phase field system in a bounded domain Ω ⊂ Rn for the dimension n ≤ 3 with a single observation on a subdomain ω {double subset} Ω and the Sobolev norm of certain partial derivatives of the solutions at a fixed positive time θ ∈ (0, T) over the whole spatial domain. The proof of these results relies on an appropriate Carleman estimate for the phase field system.
