Structural And Magnetic Properties

We prepared magnetic thin films Ni81Fe19on single-crystal Si(001) substrates via single graphene layer through magnetron sputtering for Ni81Fe19and chemical vapor deposition for graphene. Structural investigation showed that crystal quality of Ni81Fe19thin films was significantly improved with insertion of graphene layer compared with that directly grown on Si(001) substrate. Furthermore, saturation magnetization of Ni81Fe19/graphene/Si(001) heterostructure increased to 477 emu/cm3with annealing temperatureTa=400°C, which is much higher than values of Ni81Fe19/Si(001) heterostructures withTaranging from 200°C to 400°C.

A series of Ta (4 nm)/ ZnO (t nm )/ Ni 81 Fe 19 (20 nm)/ ZnO (t nm )/ Ta (3 nm) magnetic thin films were prepared on lower experimental conditions by magnetron sputtering method. Effects of ZnO layer thickness and substrate temperature on anisotropic magnetoresistance and magnetic properties of these Ni 81 Fe 19 films have been investigated. The experiment results show that the anisotropic magnetoresistance value of the Ni 81 Fe 19 film is enhanced with the increasing of the inserted ZnO layer thickness. When the ZnO thickness is 2 nm, the anisotropic magnetoresistance value achieves the maximum. In addition, the anisotropic magnetoresistance of the Ni 81 Fe 19 film is also enhanced with the increasing of substrate temperature, and when the temperature is 450°C, the anisotropic magnetoresistance reaches the maximum. The anisotropic magnetoresistance value of 20 nm Ni 81 Fe 19 films with 2 nm ZnO layer can achieve 3.63% at 450°C which is enhanced 11.6% compare with the films without ZnO layer.

Molten Salt Electrolytes

The electrodeposition of magnetic films of Co-Zn in zinc chloride-dimethylsulfone (ZnCl2- DMSO2) molten salt electrolytes with added CoCl2 has been studied. The phase diagram of ZnCl2- DMSO2 molten salts was determined by differential scanning calorimetry (DSC) and thermogravimetric analysis (TGA). Various compositions of alloys with different deposition potentials on the electrode surface have been studied by cyclic voltammetry. Either the constant potential method or the pulse potential method of plating can be used for electrodepositing Co-Zn thin films. The surface morphologies and magnetic properties have been studied. It has been shown that compact needle-type Co-Zn thin films are obtained at a constant potential of −0.1 V. Compact and uniform Co-Zn thin films are obtained by pulse electrodeposition. The magnetic properties of these films show higher coercive forces (Hc) and smoother domains than those obtained by the constant potential method.
