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.

In this work, we study the magnetic properties of nickel nanowires by measuring their anisotropic magnetoresistance at room temperature. The single nickel nanowire is grown by electrodeposition in a polymer membrane (Polycarbonate). We measure the anisotropic magnetoresistance effect of nickel nanowires for the various values of the magnitudes and orientations of an external magnetic field. The results clearly show the existence the anisotropic magnetoresistance effect in the nickel nanowires. Besides, the experimental data are best fit to the analytical calculations using the Stoner-Wohlfarth model for the magnetization of the wires.

Electrical And Magnetic Properties

Amorphous materials are of current interest due to their desirable mechanical, electrical and magnetic properties. Furthermore, crystallizing amorphous alloys provides an avenue for discerning sequential and competitive phases thus allowing access to otherwise inaccessible crystalline structures. Previous studies have shown the benefits of using AEM to determine crystal structures and compositions of partially crystallized alloys. The present paper will discuss the AEM characterization of crystallized Cu-Ti and Ni-Ti amorphous films.Cu60Ti40: The amorphous alloy Cu60Ti40, when continuously heated, forms a simple intermediate, macrocrystalline phase which then transforms to the ordered, equilibrium Cu3Ti2 phase. However, contrary to what one would expect from kinetic considerations, isothermal annealing below the isochronal crystallization temperature results in direct nucleation and growth of Cu3Ti2 from the amorphous matrix.

Iron-base alloys containing 8-11 wt.% Si, 4-8 wt.% Al, known as “Sendust” alloys, show excellent soft magnetic properties. These magnetic properties are strongly dependent on heat treatment conditions, especially on the quenching temperature following annealing. But little has been known about the microstructure and the Fe-Si-Al ternary phase diagram has not been established. In the present investigation, transmission electron microscopy (TEM) has been used to study the microstructure in a Sendust alloy as a function of temperature.An Fe-9.34 wt.% Si-5.34 wt.% Al (approximately Fe3Si0.6Al0.4) alloy was prepared by vacuum induction melting, and homogenized at 1,200°C for 5 hrs. Specimens were heat-treated in a vertical tube furnace in air, and the temperature was controlled to an accuracy of ±2°C. Thin foils for TEM observation were prepared by jet polishing using a mixture of perchloric acid 15% and acetic acid 85% at 10V and ∼13°C. Electron microscopy was performed using a Philips EM 301 microscope.
