Abstract

Owing to the relative abundance of its constituent elements and large magnetocaloric properties observed near room temperature, the AlFe2B2 system has attracted much attention recently. Here, we have studied the magnetic and magnetocaloric properties of Al0.85+xSi0.15Fe2B2 (x = 0.2, 0.4) prepared by drop-casting followed by annealing and acid treatment. The second order ferromagnetic phase transitions were observed near room temperature (∼298–305 K) and peak magnetic entropy changes (−ΔSM) of more than −6 J kg−1 K−1 were observed for a field change of 5 T. The results are discussed in terms of the impurity phases formed in the compounds due to excess aluminum.
