Abstract: To provide a suitable method of producing an ordered-alloy ferromagnetic nanowire structure. Disclosed is a method of producing an ordered-alloy ferromagnetic nanowire structure, the method including: forming a nanowire on or above a substrate, the nanowire having a width of 100 nm or less and a length of at least twice the width, and made of an iron group element and a platinum group element; and subjecting the nanowire to heat treatment to obtain an ordered-alloy ferromagnetic nanowire structure in which an ordered-alloy ferromagnetic nanowire made of an ordered alloy of the iron group element and the platinum group element is formed on or above the substrate.
