The structural and magnetic properties of essentially phase pure A1Fe2B2 prepared by arc melting were compared with a sample containing impurities.Analysis was carried out by means of synchrotron X-ray diffraction,magnetic measurements and M(o)ssbauer spectroscopy.The analysis of synchrotron X-ray diffraction data confirmed the orthorhombic structure of space group Cmmm for AlFe2B2 with Al13Fe4 as main impurity phase.The magnetic measurements revealed an unsaturated ferromagnetic state in AlFe2B2 with a transition temperature (Tc) of 286 K.Isothermal magnetization measurment at 5 K gave a saturation magnetization of 0.7 μB per Fe atom while Arrott plots establish the second order nature of ferromagnetic transition.The thermal evolution of M(o)ssbauer spectra confirmed the ferromagnetic nature of this material revealing an hyperfine field of 73 kOe and an isomer shift of 0.46 mm/s at 100 K.The M(o)ssbauer spectra of a phase pure sample was compared with the one containing impurity phases.It is suggested that the low temperature paramagnetic contribution in M(o)ssbauer spectra of phase pure material may have its origin in some intrinsic phenomena arising from defects or inhomogeneities in crystal structure.
