N2 - In this paper, we report the structural, magnetic and magnetocaloric effect (MCE) of La1-xRxFe13-yAlyC z (R = Pr and Nd, x = 0.1 and 0.2, y = 1.5 and 1.6 and z = 0.02 and 0.04) compounds. Temperature dependence of magnetization data shows second order and ferromagnetic transition for all compounds. MCE has been calculated in terms of isothermal (ΔSM) using the magnetization isotherms obtained at transition temperature close to transition temperature. The maximum values of ΔSM vary between ∼3 to ∼5 and ∼5.2 to ∼8.3 J kg-1 K-1 for a field change of 20 kOe and 50 kOe, respectively, whereas relative cooling power is ∼140 to ∼230 and ∼396 to ∼556 J kg-1 for the same field change.
