Crystallographic Studies of Nd_3-xY_xFe_27.5TM_1.5(0.6≤x≤2.4, TM=Ti, Mo) Compounds

Abstract:

Nd_3-xY_xFe_27.5Ti_1.5(0.6≤x≤2.4) and Nd_3-x’Y_x’Fe_27.5Mo_1.5 (0.6≤x’≤2.4) alloys have been synthesized successfully and studied by means of powder neutron diffraction. The structural analyses indicate that the main phases in all cases crystallize in the monoclinic Nd₃(Fe,Ti)₂₉-type structure with a space group A2/m. Ti and Mo prefer to occupy 4g, 4i1 and 4i2 sites exclusively and the elemental site occupancies are dominated by the site sizes and thermodynamic effects.
