摘要	Magnetocaloric effect near room temperature is enhanced by minor Al substitution in Mn(1-x)Al(x)As compounds (x=0. 0.015, 0.03). The Curie temperature and magnetic entropy change can be tuned by Al concentration. Under a field change of 2 T. which is below the critical field of metamagnetic transition and easy to reach in applications, a large reversible magnetic entropy change 28.5 J kg(-1) K(-1), and a huge magnetic entropy change 65.7J kg(-1) K(-1) under a field change of 5 T is obtained at x=0.015 near room temperature. Compared with that of MnAs mother alloy, it is Concluded that minor Al substitution is beneficial for enhancing the magnetic entropy in Mn(1-x)Al(x)As alloys. (C) 2008 Elsevier B.V.
