The relativistic RPA approaches are applied to calculate the charge-exchange spin flip resonances. Comparing the RPA calculations based on the relativistic Hartree and relativistic Hartree-Fock theories, the different physical mechanisms in determining the Gamow-Teller resonance are investigated. Then, the theoretical descriptions of spin-dipole and spin-quadrupole resonances are presented. In particular, the energy hierarchies of different components in these resonances are focused on.
