Abstract
The effect of the addition of 0.5 at.% Cu, Ga, Hf, V,Mo, Nb, Co, Ni, Cr, Dy or Tb on the magnetic properties and the microstructure of sintered Nd16Fe 75.22Ti1.26Al0.32B7.2 magnets has been studied. It is shown that these addi tives cause a small decrease in remanence and in intrinsic coercivity, with the exception of Cu, Dy and Tb additives, which lead to an increase in the intrinsic coercivity. The correlation between the hyperfine magnetic field and the magnetic properties of the investigated magnets is discussed. (C) 2001 Elsevier Science B.V. All rights reserved.
