Abstract: Structural and magnetic properties of La1 yNdy(Fe0.88Si0.12)13compounds have been investigated by means of X-ray diffraction and magnetization measurements. The single-phase NaZn13-type cubic structure is stabilized for the compounds withy¼0; 0.1, 0.3 and 0.4. All the synthesized compounds are ferromagnetic. Their Curie temperatureTC slightly increases with increasing Nd up toy¼0:3: The most striking effect of the Nd substitution, however, is in their itinerant-electron metamagnetic behavior and the magnetocaloric effect in the vicinity of TC: The maximum entropy change decreases somewhat, but the relative cooling power increases with increasing Nd content (i.e. fory¼0:3)
