Broken time-reversal symmetry (BTRS) in d+id^\ensuremath' as well as in d+is superconductors is studied and is shown to yield current carrying surface states. We evaluate the temperature and thickness dependence of the resulting spontaneous magnetization and show a marked difference between weak and strong BTRS. We also derive the Hall conductance which vanishes at zero wave vector q and finite frequency \ensuremathω; however, at finite q,\ensuremathω it has an unusual structure. The chirality of the surface states leads to quantum Hall effects for spin and heat transport in d+id^\ensuremath' superconductors.
