“…[1][2][3] To take full advantage of rich resources, the effort to reduce the amount of neodymium in Nd-Fe-B magnet by substituting partial Nd with cerium has been made in recent years. For economic and environmental pressures arising from the large-scale consumption of neodymium, [4][5][6][7][8][9][10] some work has been done to apply cerium to magnets. However, the crystal anisotropy field of 4.6 T of Ce 2 Fe 14 B is only approximately half that of Nd 2 Fe 14 B (7.5 T), the saturation magnetization of Ce 2 Fe 14 B (1.17 T) is substantially lower than that of Nd 2 Fe 14 B (1.61 T).…”

The influences of the spacer-layer Ta on the structures and magnetic properties of NdFeB/NdCeFeB multilayer films are investigated via DC sputtering under an Ar pressure of 1.2 Pa. An obvious (00l) texture of the hard phase is observed in each of the films, which indicates that the main phase of the film does not significantly change with Ta spacer-layer thickness. As a result, both the remanence and the saturation magnetization of the magnet first increase and then decrease, and the maximum values of 4πM r and H cj are 10.4 kGs (1 Gs = 10 −4 T) and 15.0 kOe (1 Oe = 79.5775 A•m −1 ) for the film with a 2-nm-thick Ta spacer-layer, respectively, where the crystalline structures are columnar shape particles. The measured relationship between irreversible portion D(H) = −∆M irr /2M r and H indicates that the nucleation field of the film decreases with spacer layer thickness increasing, owing to slightly disordered grains near the interface between different magnetic layers.

In this work, the microstructure, crystal structure and magnetic properties of (Nd0.7Pr0.15RE0.15)2.28Fe13.58B1.14 (RE=La, Ce, Y) alloys prepared by arc-melting were investigated experimentally. The experimental results show that all alloys annealed at 1173 K for 360 hrs contain the isotropic Nd2Fe14B structure phase. The coercivities (Hc) of (Nd0.7Pr0.15RE0.15)2.28Fe13.58B1.14 (RE=La, Ce, Y) melt-spun ribbons are 12.3 kOe, 13.2 kOe, 8.5 kOe, and the Curie temperatures (Tc) of annealed (Nd0.7Pr0.15RE0.15)2.28Fe13.58B1.14 (RE=La, Ce, Y) alloys are 569 K, 552 K and 576 K, respectively. Meanwhile, the remanences (Br) of (Nd0.7Pr0.15RE0.15)2.28Fe13.58B1.14 (RE=La, Ce, Y) melt-spun ribbons are about 67 emu/g, 74 emu/g and 72 emu/g, respectively. It was indicated that the coercivity, remanence and Curie temperatures of (Nd0.7Pr0.15RE0.15)2.28Fe13.58B1.14 alloys are dependent on light rare earth elements.
