recent trends in magnetic nanowires and submicron wires prepared by the quenching and Drawing Technique
2020Co-Authors: Tibor-adrian Óvári, Nicoleta Lupu, H. ChiriacAbstract:Abstract Glass-coated amorphous ferromagnetic nanowires and submicron wires prepared by means of rapid solidification Techniques are a novel class of ultrathin magnetically soft materials with high prospects of being employed in novel micro- and nanosensing devices and domain wall logic-based applications. The main characteristics of their magnetic bistable behavior, along with the specific aspects of the domain wall propagation, are analyzed. These phenomena are prone to be among the first operating principles for applications based on these new materials. New characterization methods, which have been specifically developed for such ultrathin wires, are also discussed, together with the future trends on this subject.

highly photo stable dye doped solid state distributed feedback dfb channeled waveguide lasers by a pen Drawing Technique
Optics Express, 2010Co-Authors: Yu Yang, Ryo Goto, Kenchi Yamashita, Hirofumi Watanabe, Masaya MiyazakiAbstract:Pyrromethene dyes doped polymeric channeled waveguide lasers with permanent DFB structures were fabricated via a novel pen-Drawing Technique with the patterned polydimethylsiloxane (PDMS) chips fabricated through a casting process as the substrates. With the high resolution dispensers, dye doped high viscosity pre-polymers were written into the PDMS grooves and the cross-section of the channeled waveguides could be controlled by both the polymer composition and the pen-Drawing parameters. Highly stable laser output with 4.8 × 106 pulses of laser lifetime at 500 Hz of pump repetition rate has been obtained, which is suggested to be among one of the best results of pyrromethene 567 (PM567) up to date.

Cold Drawing of micro Ni80Fe20/Cu composite wires
Journal of Materials Processing Technology, 2007Co-Authors: H.l. Seet, Xiaoping LiAbstract:Abstract The development of sensing elements for magnetic field sensors requires the use of soft magnetic materials. The method of cold Drawing is well suited for the production of such microwires due to its ability to produce uniformity in wires with good composition control. The objective of this study is to develop and optimize the cold Drawing Technique of composite microwires. In this study, composite microwires of external diameter 42 μm, with thickness ratios of 1:4:1 and 1:10:1, were developed. The effect of the final annealing temperature on the surface morphology of the composite wires was also investigated. This paper presents in detail the cold Drawing Technique of composite microwires. The results showed that there was a protruding effect of the Cu after the first draw and this protrusion decreased after subsequent draws in the earlier draws. Since the ratio of the diameter of the Cu core to the overall diameter remained relatively unchanged throughout the process, the rule of the conservation of volume can be used to predict the final diameter and length of the composite wire. When the annealing temperature was increased to beyond 850 °C, significant changes to the surface morphology occurred.
