Synthesis and Magnetic Properties of Ln2/3TiO3 (Ln=Pr and Nd)

A-site deficient perovskite-type compounds in the ternary CaTiO3-LaCrO3-La2/3TiO3 system

“…The structure of La 2/3 TiO 3−δ could be stabilized also with the formation of oxygen vacancies [28,30]. The A-cation deficient compounds R 1−x TiO 3 with the perovskite-like structure are known in the systems of Ce, Pr and Nd [28,29,40,[44][45][46][47]. Many other investigations of physical and chemical properties of the A-site deficient titanates were performed in the last years [48][49][50][51][52].…”

Low‐Temperature Transformations of Protonic Forms of Layered Complex Oxides HLnTiO4 and H2Ln2Ti3O10 (Ln = La, Nd)

“…Ln 2/3 TiO 3 dissolved at higher concentration and reaction does not have time to pass through at lower concentration. In case of Nd 2/3 TiO 3 pure phase of the product was obtained, while for La 2/3 TiO 3 the impurity of stable HLnTiO 4 * H 2 O phase was observed [16] (Figure 2).…”

Probing structural changes in Ca(1−x)Nd2x/3TiO3 ceramics by Raman spectroscopy

“…12 Earlier investigation of CaTiO 3 -based and A-site deficient perovskite ceramics employed a variety of space groups for structural analysis, including C2/m, 12,27 Pbnm, 12,27 P4/ mmm, 28,29 and Pmmm. 30,31 For our Ca (1Àx) Nd 2x/3 TiO 3 samples, all relevant space groups were considered. On the basis of goodness of fit (GOF) data for the X-ray diffraction spectra, all compositions (except the CaTiO 3 end member) could best be indexed on the basis of a two perovskite phase mixture with symmetries of Pbnm and C2/m.…”
