The obtained results clarify details of the structural transitions assuming the changes that occurred in the crystal lattice dynamics of the compounds. Increase in the dopant content causes a notable change in the intensity and position of the reflectance lines at 18.2 \u03bcm and 22.6 \u03bcm (550 cm\u22121 and 440 cm\u22121) ascribed to the transverse optical phonon modes associated with Bi (Nd, Gd)\u2013O and Fe\u2013O bonds. In the concentration region attributed to the dominant rhombohedral phase, the chemical substitution leads to an increase in intensity of the modes A1 for solid solutions of both systems. Meanwhile, in the case of Gd doping, the mode A1 shifts towards the red side of the spectrum, but there is an opposite tendency in the case of Nd doping; the intensity of the modes E decrease regardless of both the dopant-ion type and concentration. This behavior is discussed assuming the change in mass for the chain of chemical bonds caused by different dopant ions and the structural transformations occurring in the compounds upon chemical doping.<\/jats:p>","DOI":"10.3390\/magnetochemistry8090103","type":"journal-article","created":{"date-parts":[[2022,9,16]],"date-time":"2022-09-16T01:35:10Z","timestamp":1663292110000},"page":"103","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Structure and Lattice Dynamics of Bi1\u2212xNdxFeO3 and Bi1\u2212xGdxFeO3 Ceramics near the Morphotropic Phase Boundary"],"prefix":"10.3390","volume":"8","author":[{"given":"Valery R.","family":"Sobol","sequence":"first","affiliation":[{"name":"Faculty of Physics and Mathematics, Belarusian State Pedagogical University, 220030 Minsk, Belarus"}]},{"given":"Kazimir I.","family":"Yanushkevich","sequence":"additional","affiliation":[{"name":"Scientific-Practical Materials Research Centre of NAS of Belarus, 220072 Minsk, Belarus"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0008-0525","authenticated-orcid":false,"given":"Siarhei I.","family":"Latushka","sequence":"additional","affiliation":[{"name":"Scientific-Practical Materials Research Centre of NAS of Belarus, 220072 Minsk, Belarus"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9748-3939","authenticated-orcid":false,"given":"Dmitry V.","family":"Zhaludkevich","sequence":"additional","affiliation":[{"name":"Scientific-Practical Materials Research Centre of NAS of Belarus, 220072 Minsk, Belarus"}]},{"given":"Kapiton N.","family":"Nekludov","sequence":"additional","affiliation":[{"name":"Institute of Advanced Materials and Technologies, National Research University of Electronic Technology \u201cMIET\u201d, 124498 Zelenograd, Moscow, Russia"}]},{"given":"Maxim V.","family":"Silibin","sequence":"additional","affiliation":[{"name":"Institute of Advanced Materials and Technologies, National Research University of Electronic Technology \u201cMIET\u201d, 124498 Zelenograd, Moscow, Russia"},{"name":"Scientific-Manufacturing Complex \u201cTechnological Centre\u201d, 124498 Zelenograd, Moscow, Russia"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3040-8878","authenticated-orcid":false,"given":"M.
