The Co/Pt multilayers film was deposited on monocrystal Si(111) using electrocrystallization in boric acid system, in which Pt(NO2)2(NH3)2 and CoSO4 were used as main salts. The cross section morphology of the multilayers was characterized by SEM method. The results showed that a periodically layered structure was obtained by electrodeposition. In Co/Pt interface, CoPt3 was found by middle angle X-ray diffraction method. The hysteresis loop of the multilayers was determined by PPMS method. The result showed that the coercivity of multilayers was about 165 Oe parallelly, and the coercivity in perpendicular increased with the content of Co, 396 Oe at a maximun. The Co/Pt multilayer with the easy-magnetization axis perpendicular to the face of layers was firstly prepared by electrocrystallization method.

Key words: electrocrystallization, multilayer, X-ray diffraction, hysteresis loop, perpendicular magnetic anisotropy
