In this presentaion, we investigated the current-induced spin-orbit torque in the system of Py/Pt/Co trilayer structure which perpendicularly magnetized Pt/Co system is deposited on the in-plane magnetized Py layer. Through the Hall measurement using ac-current, we observed an unconeventional torque acting on Py layer which the polarity of the torque depends on the magnetization vector of Co layer.
