Abstract

The magnetic properties and magnetic entropy changes of the LaFe_11.0Co_0.8(Si_1-xAl_x)_1.2 (x=0, 0.2, 0.4, and 0.6) compounds have been experimentally studied. The Curie temperature is found to increase with increasing Al concentration from 276 K for x = 0 to 290 K for x = 0.6. The maximum magnetic entropy change {divides}ΔS{divides} under a field change of 0-5 T reduces from 18.5 to 8.8 J/kg K as x increases from 0 to 0.6, whereas the full-width at half-maximum of {divides}ΔS{divides}, δT_FWHM, increases from 27 to 51 K.
