We study an inverse problem for the Schr?dinger equation in a bounded Lipschitz domain ? ? Rn, n ? 3 when both magnetic and electric potentials are present. We prove that the divergence-free component of the magnetic potential A and the electric potential q can be uniquely recovered from the Dirichlet-to-Neumann map provided A L? (?)n, q L? (?), the normal component of the divergence-free part of A is zero on ??, and ||A||? (1 + diam (?)) is sufficiently small. In order to prove uniqueness, we construct special quasi-exponential solutions for elliptic equations of the form ?u + b ? ?u + cu = 0, assuming that b L? (?)n, c L? (?), and b is sufficiently small.
