%X A magnetic layered inorganic-inorganic composite involving manganese zinc ferrite (Mn0.8Zn0.2Fe2O4) and Mg-Al layered double hydroxides (MgAl-LDHs) was assembled by coprecipitation method. The products were characterized by TEM, FTIR, DTA, XRD and VSM. The results indicate that the composite has core-shell structure, the introduction of ferrite particles does not change the typical layered-structure of MgAl-LDHs phase. MgAl-LDHs has infinitely small magnetic shielding effect on ferrite particles, the saturation magnetization values of the composite increase linearly with the ferrite content, however, is the MgAl-LDHs content increasing, the ceorcivity values of the composite decrease first, then increase subsequently, but these changes are small on the whole. In addition, the LDHs layer also has infinitely small effect on the thermomagnetic effect of ferrite particles. It is obvious that the ferrite content in the composite plays a decisive role on magnetic properties and thermomagnetic effect.
