Abstract
An explanation is given to an unusual magnetic field dependence of Hall voltage of NiS 2 at 4.2 K which has been already reported [Trans. Japan Inst. Metals 18 (1977) 590]. To perform this more completely transverse magnetoresistance, magnetic torque and Hall voltage (changing magnetic field direction in (110) plane) were measured at 4.2 K. Planar Hall effect was also examined and was shown to have little influence on Hall voltage. An L -vector and (weak-) ferromagnetization are introduced as a difference and a sum of two sublattice magnetizations respectively. A phenomenological formula for galvanomagnetic effect is extended to the case that the L -vector and ferromagnetization are included as an argument besides magnetic field. Under some assumptions for weakferromagnetic domain distribution, Hall voltage is well reproduced by the quadratic term of the L -vector.
