Title: Effects of Al content and annealing on the phases formation, lattice parameters, and magnetization of A l x F e 2 B 2 ( x = 1.0 , 1.1 , 1.2 ) alloys

Abstract

AlFe2B2 is a ferromagnet with the Curie temperature around 300 K and has the potential to be an outstanding rare-earth free candidate for magnetocaloric applications. However, samples prepared from the melt contain additional phases which affect the functional response of the AlFe2B2 phase. Here, we report on the effects of Al content in samples with the initial (nominal) composition of AlxFe2B2 where x=1.0, 1.1, and 1.2 prepared by arc-melting followed by suction casting and annealing. The as-cast AlxFe2B2 alloys contain AlFe2B2 as well as additional phases including the primary solidifying FeB and Al13Fe4 compounds which are ferromagnetic and paramagnetic, respectively, at 300 K. The presence of these phases makes it difficult to extract the intrinsic magnetic properties of AlFe2B2 phase. Annealing of AlxFe2B2 alloys at 1040°C for 3 days allows for reaction of the FeB with Al13Fe4 to form the AlFe2B2 phase, significantly reduces the amount of additional phases, and results in nearly pure AlFe2B2 phase as confirmed with XRD, magnetization, scanning electron microscopy, and electronic transport. The values of the magnetization, effective magnetic moment per Fe atom, specific heat capacity, electrical resistivity and Seebeck coefficient for the AlFe2B2 compound have been established.
