Fabrication and magnetic properties of metallic nanowires via AAO templates

Magnetic micropillar sensors for force sensing

“…The nanocomposite is fabricated by mixing the NWs with the polymer and then curing the composite. The NWs can be aligned in a certain direction by applying an external homogenous magnetic field during the curing process (8).…”

“…However, these particles require a high magnetic field for magnetization, which increases the power consumption and limits the possibility of integration and miniaturization. On the other hand, iron nanowires (NWs) have a high magnetization in the absence of a magnetic field, due to the strong shape anisotropy, and they can be easily fabricated with a cost effective process [8]. Incorporating these NWs in a polymer results in a permanent magnetic composite with distinct features and reinforced mechanical properties [9].…”

Toward uniform electrodeposition of magnetic Co-W mesowires arrays: direct versus pulse current deposition

“…Pulse plating has been satisfactorily used by several authors to fill all the pores of anodic aluminum oxide (AAO) templates with various metal nanowires (e.g., Ni or Co) [11,12]. During the study of Co [4][5][6][7][13][14][15][16][17][18][19][20], Ni [5,16,19,[21][22][23], and their alloys [24][25][26] it was concluded that the quality of the resulting wires strongly depends on the duty cycle. A relatively long pause between the pulses is preferable.…”

Controlling the anodizing conditions in preparation of an nanoporous anodic aluminium oxide template

“…Nanoscale porous surfaces are extensively demanded for both nanoscience and nanotechnology as templates [20], for the synthesis of metallic alloy, oxide and semiconductor one-dimensional nanostructures [21][22][23][24][25]. One-dimensional nanostructures, employing the AAO template, are very attractive for various applications [26][27][28][29]. An AAO template is a closepacked array of hexagonal parallel and cylindrical cells with a pore in the center of each cell [30].…”
