Abstract

Magnetization, electrical resistivity, thermoelectric power and magnetoresistance were measured for the ordered alloys Fe_2+xV_1-xAl (0≤x≤0.4). The magnetization measurement shows that the phases are ferromagnetic. Both the Curie temperature and the spontaneous magnetization increase with increasing x. The samples with x≤0.1 exhibit a semiconductor-like behavior. Energy gap E_G decreases with increasing x. The electrical resistivity versus temperature curves make a broad maximum near T_C for the samples with x = 0.18, 0.20 and 0.40. For Fe_2.18V_0.82Al, negative large magnetoresistance is observed.
