“…Sm-Co, L1 0 CoPt, Nd-Fe-B, MnBi) are sensitive to thermal processing conditions [298,302,310,311,327,332], which leads to many challenges in achieving and retaining a high energy density. For instance, a high temperature anneal around 600 • C is known to obtain a high coercivity in sintered Nd-Fe-B magnets [326,331], while a magnetic field anneal can induce a preferred orientation of the crystal [307].…”
