A METHOD FOR FABRICATING FE(1-X)COXSI NANOWIRE AND FE(1-X)COXSI NANOWIRE PREPARED THEREBY

摘要

A method for manufacturing iron cobalt silicide nanowires is provided to produce high-purity and high-quality single crystal iron cobalt silicide(Fe_(1-x)Co_xSi) having physical properties suitable for applications to nano devices. An iron cobalt silicide single crystal nanowire has a composition of Fe_(1-x)Co_xSi, wherein x is a value ranging from 0.01 to 0.99. A method for manufacturing the iron cobalt silicide single crystal nanowire includes a step of heat-treating a precursor placed at the front end part of a reactor and a silicon substrate placed at the rear end part of the reactor under an inert gas atmosphere to form the Fe_(1-x)Co_xSi nanowire on the silicon substrate, wherein the precursor is a mixture of cobalt halide and iron halide. Further, the nanowire is ferromagnetic material and has helical spin order.
