An explanation is given to an unusual magnetic field dependence of Hall voltageof NiS. at 4.2 K which has been already reported [Trans. Japan Inst. Metals 18(1977) 5904. To perform this more completely transverse magnetoresistance,magnetic torque and Hall voltage (changing magnetic field direction in (l 10) plane)were measured at 4.2 K. Planar Hall effect was also examined and was shown tohave little influence on Hall voltage. An L-vector and (weak-) ferromagnetizationare introduced as a difference and a sum of two sublattice magnetizations respec-tively. A phenomenological formula for galvanomagnetic effect is extended to thecase that the L-vector and ferromagnetization are included as an argument besidesmagnetic field. Under some assumptions for weakferromagnetic domain distri-button, Hall voltage is well reproduced by the quadratic term of the L-vector.
