  Using ground state computations, we study the transition from a spin glass to
a ferromagnet in 3-d spin glasses when changing the mean value of the spin-spin
interaction. We find good evidence for replica symmetry breaking up till the
critical value where ferromagnetic ordering sets in, and no ferromagnetic spin
glass phase. This phase diagram is in conflict with the droplet/scaling and
mean field theories of spin glasses. We also find that the exponents of the
second order ferromagnetic transition do not depend on the microscopic
Hamiltonian, suggesting universality of this transition.
