We investigated the perpendicular magnetic anisotropy and the Hall resistivity of CoSiB/Pd multilayers. The CoSiB/Pd multilayers consisted of CoSiB (7- thickness) and Pd (Pd thickness t (Pd) = 10, 12, 14, 16, 18, and 20 ), and a CoSiB/Pd bilayer was stacked five times. The coercivity shows oscillating values between tPd = 12 and t (Pd) = 20 . The value of the saturation magnetization increased between t (Pd) = 10 and t (Pd) = 12 and then decreased after t (Pd) = 12 . The perpendicular magnetic anisotropy constant depended on the thickness of Pd-layer and the values repeatedly increased and decreased. All CoSiB/Pd multilayers exhibited a positive Hall effect, and the Hall resistivity was not proportional to the magnetic moment.
