"Alloys of composition Nd10.8Dy0.75Tb0.75Fe79.7-xCoxZr0.8Nb0.8Cu0.4B6.0 (x = 0, 3, 6, 9, 12, 15) were prepared by melt spinning at 22 m/s and subsequent annealing. Phase analysis revealed single-phase materials," researchers in Beijing, People's Republic of China report.
"Magnetic structure and remanence analysis indicated strong exchange coupling between neighboring grains in all samples. The remanence polarization J(r) and maximum energy product (BH)(max) increased first and then decreased with further increasing Co content x although the intrinsic coercivity H-ci decreased with increasing x. The increase in remanence polarization J(r) by the substitution of Co ...
