Magnetic properties of sintered Nd-Y-Fe-B magnets

The effect of a partial substitution of Nd by Y on the properties of sintered Nd 15- x Y x Fe 77B 8 magnets has been investigated. With increasing Y concentration the density of the magnets decreases slowly, whereas the saturation polarization and the Curie temperature are not changed significantly....

Description
Summary:The effect of a partial substitution of Nd by Y on the properties of sintered Nd 15- x Y x Fe 77B 8 magnets has been investigated. With increasing Y concentration the density of the magnets decreases slowly, whereas the saturation polarization and the Curie temperature are not changed significantly. The decrease of the coercivity is correlated with the decrease of the anisotropy field strength.
