摘要	In this work, cooling fields (H-FC) with different signs or magnitudes were applied on ferromagnetic (FM)/antiferromagnetic (AF) films [Pt(10 angstrom)/Co(4 angstrom)](4)/NiO(t(Nio) angstrom) when FM magnetization of Pt/Co multilayers was kept in positive saturation state at room temperature. Compared to results at H-FC=+5 kOe, it is seen that H-FC= -1 kOe suppressed the exchange bias field (H-E) and enhanced the coercivity (H-c) at the same time. The phenomenon indicates that AF spins can be modified by cooling field without changing the FM magnetization. The experimental results are understood by the competition between the FM/AF interfacial exchange coupling and Zeeman energy in FM/AF systems with ferromagnetic interfacial coupling.
