Magnetic properties of the Fe-Nd-Al alloys prepared by suction casting
The magnetic properties of the Fe (x) Nd90 -x Al-10 (x = 30, 40, 43, 50, 53) alloys prepared by suction casting were investigated. The intrinsic coercivity (H-i(c)) decreases significantly with the substitution of Fe for Nd. The Fe53Nd37Al10 (x = 53) alloy shows soft magnetic behavior, which contains Fe-rich (Fe75Nd18Al7) crystalline phase and Nd-rich (Fe28Nd59Al13) amorphous phase. The Nd-rich amorphous phase in the Fe53Nd37Al10 alloy exhibits soft magnetic behavior. However, the Nd-rich bulk amorphous alloy of the same composition prepared by suction casting shows hard magnetic behavior. The interesting phenomenon is discussed.
