Expressions of the temperature-dependent parallel and perpendicular nuclear moments of inertia including neutron-proton pairing correlations have been established. The latter have been derived using the cranking method as well as the isovector temperature-dependent gap equations [1]. They generalize the expressions of the usual finite-temperature BCS (FTBCS) method. The model has been applied to the schematic Richardson model. The obtained results are compared to those of the usual FTBCS approach for the pairing between like-particles.
