The Ni-Fe and Mg-Al-Fe-LDH show paramagnetism at normal temperature, the calcined samples of LDHs show super-paramagnetism. The magnetization increases with the higher Fe~(3+) content and is independent of the crystal structure of LDHs. Magnetization of the calcinates of Ni-Fe-LDHs is higher than the Mg-Al-Fe-LDHs.3. Two novel SFME systems were found for the first time, that is furaldehyde/DMF/water and furaldehyde/ethanol/water system.

结果表明，Ni-Fe和Mg-Al-Fe型LDHs本身及其煅烧产物在常温下均呈现顺磁性，其煅烧产物均呈现超顺磁性；同类LDH中其煅烧产物的磁性大小与Fe~(3+)含量成正比而与LDH的晶体结构无关，Ni-Fe LDHs及其煅烧产物的磁性强于Mg-Al-Fe LDHs及其煅烧产物，。3。
