中文摘要	This study investigated the magnetism and anomalous transport properties of the melt-spun ribbon Fe2MnAl alloy. It is found that the alloy exhibits ferromagnetic order with the Curie temperature of similar to 150K, followed by another magnetic transition at T-R similar to 51 K. It is suggested there is antiferromagnetism pinning effect on the ferromagnetic matrix at the temperature below T-R. A steep rise of the resistance below T-R has been observed, which can be understood in terms of antiferromagnetic scattering. An appearance of the resistance maximum near the Curie temperature and the negative temperature dependence of the resistance above Curie temperature are associated with the magnetic phase transition from ferromagnetism to paramagnetism. A negative magnetoresistance at low temperature arising from inhomogeneous magnetic scattering is reported. (C) 2011 Elsevier B.V. All rights reserved.
