Abstract : This article extends previous studies on the effect of tensor terms in the Skyrme energy density functional by the breaking of time-reversal invariance. We have systematically probed the impact of tensor terms on properties of superdeformed rotational bands calculated within the cranked Hartree-Fock-Bogoliubov approach for different parametrizations covering a wide range of values for the isoscalar and isovector tensor coupling constants. We analyze in detail the contribution of the tensor terms to the energies and dynamical moments of inertia and study their impact on quasiparticle spectra. Special attention is devoted to the time-odd tensor terms, the effect of variations of their coupling constants, and finite-size instabilities.
