“…In addition, as SmCo 5 phase has high anisotropy field (>200 kOe) and Sm 2 Co 17 has high magnetic dipole moment (23.2 B ) [19], therefore, nanocomposite Sm-Co/Fe(Co)-based magnets composed of hard magnetic phases of Sm 2 Co 17 or SmCo 5 and soft magnetic phases of Fe or Co have gained much attention in recent years for potential applications at elevated temperature due to high magnetic energy product. Many efforts have been devoted to produce nanocomposite powders, thin films, and rapidly quenched ribbons [20][21][22][23][24]. Rapidly quenched ribbons generally need to be crystallized to reduce amorphous phase.…”
