The combined effect of nonmagnetic and magnetic defects and impurities on the critical temperatures of superconductors with different anisotropies of the gap is studied theoretically within the weak coupling limit of the BCS model. An expression is derived which relates the critical temperature to the relaxation rates of charge carriers on non-magnetic and magnetic scatterers and to the coefficient of anisotropy of the superconducting order parameter on the Fermi surface. The particular cases of d -wave, ( s + d )-wave, and anisotropic s -wave superconductors are briefly discussed.
