| dc.description | In this work, we examined the effects of the of Nd by Ce substitution and of the nitrogenation in the structural and hyperfine magnetic properties of (Nd1-xCex)1.1Fe10CoTi with x?=?0, 0.5 and 1 systems. The alloys were prepared, with high pure elements, by arc-melting and the pieces were then homogenized at 1100 ?C for 48 h. The nitrogenation was carried out at 450 ?C for 1 h with a pressure of 0.1 MPa. The X-ray diffraction analysis allowed to identify the ThMn12-type structure mainly with average weigh fraction of 68%. The obtained tetragonal ThMn12 structure type presented an increased lattice parameter after nitrogenation for all alloys. The rhombohedral structure Th2Zn17-type is also present in the alloys and their lattice parameters do not show important changes after the nitrogenation. The M?ssbauer spectra were fitted with seven sextets and a small quadrupolar component, the sextets were associated to the Fe sites in the ThMn12-type and Th2Zn17-type phases. The mean field, ?Bhf?, improve for all alloys after nitrogenation process. The Nd1.1Fe10CoTi (x?=?0) and (Nd0.5Ce0.5)1.1Fe10CoTi (x?=?0.5) alloys that present weigh fractions of 75 and 73%, respectively, with the ThMn12?type tetragonal structure present a ?Bhf? of 30.9 and 31.0 T, respectively, after nitrogenation. Then, they can be possible candidates for rare earth-lean permanent magnets. | |
