“…In the past decades, nanostructured magnetic materials have attracted intensive interest because of their excellent physical, catalytic, magnetic properties and their crucial applications in diverse fields, including catalysts [1], biomedical treatments and analysis [2], magnetic fluids [3], magnetic photonic crystals [4,5], high-density magnetic storage media [6,7], microwave absorbing materials [8][9][10][11], high-frequency soft magnetic materials [12][13][14][15][16]. In particular, the rapid developments of wireless communication devices have required miniature magnetic components, such as inductor and transformer, to be operated at high frequency.…”
