ANGULAR DEPENDENCE OF MAGNETIC PROPERTIES IN Co NANOWIRE ARRAYS

Luu Van Thiem

Abstract


The Co nanowire arrays were fabricated by electrodeposition method by using the porous polycarbonate template. Study on crystallographic structure, micro structure, and the element composition confirmed the quality of the fabricated Co nanowires. SEM image shows the wires with an average diameter of 200 nm and the average length of 9 mm. The magnetic properties, measured at room temperature using vibrating sample magnetometry (VSM), displays that the nanowires have anisotropic property. The angular dependence of coercivity of Co nanowires has been studied. The decrease of the coercivity, when the angular changed from 0 o to 90 o, will be discussed.

 


Keywords
