FIBROUS MAGNETIC STRUCTURE AND MANUFACTURING METHOD THEREOF

Provided are a fibrous magnetic structure and a manufacturing method thereof. The manufacturing method of the fibrous magnetic structure comprises the steps of : preparing a magnetic core fiber including a rare earth element and a core transition metal element; arranging catalyst particles on the magnetic core fiber, and forming a magnetic shell surrounding the magnetic core fiber by using the catalyst particles as a plating process using a base source including a first precursor including a first shell transition metal element and a second precursor including a second shell transition metal element, and including a compound of the first shell transition metal element and the second shell transition metal element.
