Abstract
The structure, magnetic properties and the Fe-57 Mossbauer effect of L uFe11-xAlxTi alloys were investigated in the temperature range of 4.2- 500 K. The system exists as a single phase for the x < 4 concentration range. The lattice parameters follow Vegard's law. It has been found that these alloys are ferromagnetic with Curie points and magnetic mom ents decreasing with an increase in Al concentration, x. The Fe atoms are substituted by the Al atoms mostly in the 8(i) positions and a dim inution of hyperfine interaction results from a decrease in the averag e number of the nearest neighboring Fe atoms.
