Abstract: Provided is a method for manufacturing a magnetic nano-structure. The method for manufacturing a magnetic nano-structure may comprise the steps of: preparing a source solution containing a first precursor including a rare-earth element, a second precursor including a transition metal element, and a third precursor including Fe; electrospinning the source solution to form a preliminary magnetic nano-structure containing a rare-earth oxide, a transition metal oxide, and a Fe oxide; and reducing the preliminary magnetic micro-structure to manufacture a magnetic nano-structure containing an alloy composition of the rare-earth element, the transition metal element, and the Fe.
