纳米金属/介孔TiO2复合体磁性
Magnetic properties of nanosized metals/TiO2 mesoporous composites
【摘要】 本文研究了不同纳米金属含量对溶胶-凝胶法制备的纳米Fe,Co,Ni/介孔TiO2复合体的饱和磁化强度、剩余磁化强度、矩形比和矫顽力的影响。通过振动样品磁强计对纳米复合分体磁学参量(-7.96×105A.m-1<H<7.96×105A.m-1)进行测定;结果表明:纳米金属含量对复合体的磁学参量有着复杂的影响。
【Abstract】 In this paper,the effects of different nano-metal contents on the saturation magnetization,remanient magnetization,rectangular ratio and coercivity of Fe,Co,Ni/ mesoporous TiO2 composites prepared by sol-gel method.The magnetic properties including magnetic hysteresis loop and related parameters were measured by vibrating sample magnetometer(-7.96×105A·m-1<H<7.96×105A·m-1).The results show that the magnetic properties of TiO2 mesoporous composites respond to the change of nano-metal content complexly.
