Abstract: By using stepwise hydrothermal synthesis methods, magnetic materials Fe₃O₄and SmCo₅were successfully assembled into the channels of zeolites ZSM-5, Naβ and NaY, whose apertures were 0. 56, 0. 73 and 0. 78 nm, respectively. Furthermore, their magnetic hysteresis loops and magnetism parameter, M_s, M_rand H_cwere determined satisfactorily. After being assembled, the coercivity H_cof block crystal Fe₃O₄was reduced from 8117 to 1114 A/m, while the coercivity Hc of block crystal SmCo₅was reduced from 55863 to 5491 A/m. That shows the nanometer noncrystal soft magnetic materials are formed. It was caused by the quantum size effect of the nanometer particle. It was proved that the magnetic materials Fe₃O₄and SmCo₅were assembled into the channels of the zeolites by XRD, IRand magnetic hys teresis loops.
