| dc.description | <sup>57</sup>Fe Mossbauer effects of YFe<sub>11</sub>Ti with the ThMn<sub>12</sub> structure have been studied in a temperature range of 77-550 K. This material may be considered as the prototype of similar systems with yttrium replaced by a magnetic rare earth. The results show that the largest hyperfine field is on the 8i site and the smallest on the 8f site. The hyperfine fields are 23.5 T, 21.8 T and 20.2 T, the quadrupole splittings are 0.32, -0.17 and 0.27 mm s<sup>-1</sup> and the spectrum shifts are 0.01, -0.40 and -0.11 mm s<sup>-1</sup> for the 8i, 8j and 8f sites at room temperature. The quadrupole splittings are 0.29, 0.51 and 0.63 mm s<sup>-1</sup> and the spectrum shifts are -0.27, -0.48 and -0.31 mm s<sup>-1</sup> from the paramagnetic spectrum at a temperature of 550 K. Almost all Ti atoms occupy the 8i site according to the subspectral area ratios of 2.9:4.2:3.9 for the 8i, 8j and 8f sites. With increasing temperatures, H<sub>HF</sub>(T)/H<sub>HF</sub>(77 K) decreases the most slowly for the 8j site and the most rapidly for the 8f site. |
