Micrographic images before and after corrosion were obtained. The corresponding corrosion parameters in ChCl-Oxalic acid and ChCl-Malonic acid were calculated. The crystal structure was studied before and after the corrosion process by using X-ray diffraction method. The specific magnetization was investigated by ponderomotive method.
