  • Abstract
    In this study, the effect of gallium (Ga) for Al substitution in the Nd60Fe30Al(10-x)Gax (in at.%) system was analyzed. Cylindrical samples (rods) with a diameter of 1 mm were prepared by casting the material into a copper die. Substitution of gallium for aluminum leads to substantial growth of the coercivity up to 407 kA/m for x = 8. The remanence is constant up to x = 8. Magnetic properties for higher Ga concentrations of hard magnetic properties abruptly decrease. On the basis of the differential scanning calorimeter and X-ray diffraction data, it may be concluded that the Ga addition reduces the ability for amorphous structure formation; for x = 10 crystalline phases predominate.
