New type materials were designed with magnetic fluid fields. Magnetic iron oxide were synthesized by the initial materials of (FeCl)_2 and (FeCl)_3 in Ar gas ambiance and at the same time, these magnetic iron oxide of ultrafine particles were coated by Mono-saccharide (D-glucuronic acid, etc) in solvent. Those were named to D-glucuronic acid magnetite (GM) complex by us. GM complex were synthesized by various conditions and several steps those were given as under. At first, GM complex powder were cleared having superparamagnetism property by VSM. Next, saturation magnetization caused difference by into the covered material. Last, molecular weight and operating particle distribution could be controlled particle size. But, into the covered material weight made difference for distribution of particle size. As these results, particle size and saturation magnetization on those materials were possible to be controlled.
