A four-level N-type atomic configuration driven by two interacting control fields and a probe field. Control fields are used to manipulate and control the spin density of the probe field and its spin angular momentum vector field arrows. Significant variation of spin density of probe field is investigated with the angle between two interfering waves and the Rabi frequency of the control field. Spin distribution and spin density of circularly, diagonal, and linearly polarized probe light field is coherently controlled and modified. The control field parameters and probe field detuning play important roles in the modification of spin density and spin vector field distribution of the probe field. The modified works of this manuscript are useful for unidirectional optical interfaces and the quantum spin Hall effect of the light beam.
