Herein,we reported the fabrication of novel ZnLa0.02Fe1.98O4/PPy core-shell NPs,where ZnLa0.02Fe1.98O4 was selected as the core because of its special magnetic properties[1].Special heat capacities of the sample were determined by adiabatic calorimetry in the temperature range of 78-400 K.Thermal stability of the sample was studied by TG technology.The sample showed special magnetic and electrical properties and higher capacity in removal of methyl orange from water than that of ZnLa0.02Fe1.98O4.
