| 中文摘要 | ternary conip nanowire (nw) arrays have been synthesized by electrochemical deposition inside the nanochannels of anodic aluminum oxide (aao) template. the conip nws deposited at room temperature present soft magnetic properties, with both parallel and perpendicular coercivities less than 500 oe. in contrast, as the electrolyte temperature (t-elc) increases from 323 to 343 k, the nws exhibit hard magnetic properties with coercivities in the range of 1000-2500 oe. this dramatic increase in coercivities can be attributed to the domain wall pinning that is related to the formation of ni and co nanocrystallites and the increase of p content. the parallel coercivity (i.e. the applied field perpendicular to the membrane surface) maximum as high as 2500 oe with squareness ratio up to 0.8 is achieved at the electrolyte temperature of 328 k. it has been demonstrated that the parallel coercivity of conip nws can be tuned in a wide range of 200-2500 oe by controlling the electrolyte temperature, providing an easy way to control magnetic properties and thereby for their integration with magnetic-micro-electromechanical systems (mems).
