Possibility of preparing of an alkali-atom's state with non-zero magnetic moment and zero spin-polarization was demonstrated in this work. There are zero average values of Pauli spin operators for all coordinates in the case. We suggest using a biharmonic laser field for preparing such states. Moreover both components of the laser field should be set to resonance with two sublines in D1 line of the alkali and have circular polarization. The amplitudes of the components needed to prepare the observed states was found. It is found interesting that polarization of the components of the laser may be orthogonal or parallel for preparing the states.
