摘要:

Magnetic properties and magnetocaloric effect (MCE) in LaFe11.5Si1.5 B (0.2) have been investigated by substituting 30 % Pr for La. It is found that the substitution of 30 % Pr for La leads to a reduction in Curie temperature (T (C)) from 200 to 190 K. The characteristic of the itinerant electron metamagnetic (IEM) transition above T (C) becomes more prominent with the substitution of 30 % Pr for La. The maximum magnetic entropy change (-Delta S (M)) is remarkably enhanced from 13.0 to 17.9 J/kg center dot K under a field change of 0-3 T, and correspondingly, the values of refrigerant capacity (RC) for LaFe11.5Si1.5 B (0.2) and La0.7Pr0.3Fe11.5Si1.5 B (0.2) are 167 and 224 J/kg, respectively. The large -Delta S (M) and the high RC in a low magnetic field indicate that La0.7Pr0.3Fe11.5Si1.5 B (0.2) may be a promising candidate for magnetic refrigeration material near 200 K.
