  We introduce the notion of PT-symmetry in magnetic nanostructures and show
that they can support a new type of non-Hermitian dynamics. Using the simplest
possible set-up consisting of two coupled ferromagnetic films, one with loss
and another one with a balanced amount of gain, we demonstrate the existence of
a spontaneous PT-symmetry breaking point where both the eigenfrequencies and
eigenvectors are degenerate. Below this point the frequency spectrum is real
indicating stable dynamics while above this point it is complex signaling
unstable dynamics.
