Without magnetic field the dependence Δσ (In T) is determined by the total contribution from both effects. As the magnetic field increases, the localization contribution to Δσ decreases and at certain field values it is essentially absent so that the character of Δσ (In T) dependence is determined only by the interaction effect.
