“…In the current investigation, it was found that at lower temperatures as described by Dubok et al. C is not the only phase. With respect to the general stability of C‐phase at lower temperatures in oxides of one or two rare earth elements it is unlikely to form pure C‐phase by elevating the temperature.…”

“…Thus the LaYO 3 sample of Dubok et al. cannot show the equilibrium of a temperature between 1850 and 1900 °C, and this is also the case for the sample of NdLuO 3 . Furthermore, the formation of pure C‐NdLuO 3 after this thermal treatment would be surprising.…”

The phase relations in the system with the overall chemistry Nd 2 O 3 :Lu 2 O 3 around 1:1 were investigated by x-ray diffraction (XRD) of annealed powders and by differential thermal analysis (DTA). A mixture of rare earth oxide solid solutions in the cubic C and in the monoclinic B rare earth oxide structure was determined in the temperature range 1200 to 1650°C. The C-phase is dominated by Lu content while the B-phase is Nd rich. With rising annealing temperature, the portion of Nd in the C-phase is increased and lowered for the B-phase. Different facilitation possibilities for P-NdLuO 3 perovskite formation were discussed and examined but no evidence for stability of this phase could be found experimentally. Two thermal signals of phase transitions were detected. The first occurs at 1908°C and disappears in second heating run if the temperature is raised too much. Furthermore, a second one was detected at 2121°C.

“…13 Tompsett et al investigated LGO employing Raman spectroscopy and observed a total of 18 bands of 21 allowed modes predicted for this structure by group theory. 14 Dubok and coworkers studied the electro physical properties and nature of this interlanthanide oxide and reported the temperature dependence of resistivity in air and conduction activation energy (1.8 eV) in the range 1000-1600 C. 15 There are a few reports on dielectric properties of oxide interlanthanide ceramics, LaYbO 3 (Ref. 16) and LaAlO 3 .…”

The temperature and frequency dependent dielectric properties and leakage conduction mechanism in LaGdO3 (LGO) ceramics have been studied, and this material has been identified as a potential high-k candidate for the future complementary metal-oxide-semiconductor (CMOS) and dynamic random access memory (DRAM) technology nodes. The dielectric constant and the loss tangent at 100 kHz were ∼21.5 and ∼0.003, respectively, at ambient conditions without any significant temperature and voltage dependence. The ac conductivity shows the typical features of universal dynamic response (UDR) and obey the double power law σac=σdc+Aωn1+Bωn2 with three types of temperature dependent conduction processes involved; (i) a dc plateau (< 3 kHz) due to long range translational hopping, (ii) a mid frequency region due to the short range hopping (3–100 kHz), and (iii) a high frequency region due to localized or reorientational hopping (100–1000 kHz). The temperature dependent dc conductivity follows the Arrhenius relation with activation energies of 0.05 eV in the 200–400 K range and 0.92 eV in the 400–600 K range. The leakage current behavior reveals bulk limited Poole-Frenkel (PF) conduction mechanism and the estimated optical dielectric constant (ɛ∞) is 3.6.
