Electrical resistivities of single-crystal PrTiO3 and NdTiO3. Magnetic properties of PrTiO3, NdTiO3, PrScO3, and NdScO3

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

“…This result means a considerably larger J value in the present system, considering that the z is roughly 2/3 times as large as that of PrScO , though the origin of this di!erence is ambiguous. In another similar perovskite, NdScO , a considerably similar value, 32 K, was obtained (12). Close values were also found for PrTiO (49 K (12)) and Nd \V TiO (&45}76 K, x"0, 0.05, and 0.1 (14)), though the Ti> moments might play an important role in these systems.…”

“…For a comparably similar perovskite PrScO , where the magnetic ions are only in the lanthanide site, this value is calculated as 3.27 /Pr (12). Also, for some other oxide systems, they were found to be &10% less than those of the free ions (12). The present result means that the crystal "eld hardly a!ects the ionic state of Pr> in Pr TiO .…”

“…In some perovskite oxides, the localized moments were reported to be slightly smaller than that of the free ion value due to the crystal "eld (12). For a comparably similar perovskite PrScO , where the magnetic ions are only in the lanthanide site, this value is calculated as 3.27 /Pr (12). Also, for some other oxide systems, they were found to be &10% less than those of the free ions (12).…”

“…The result almost did not vary when the in#uence of the Ti> moments was included. In some perovskite oxides, the localized moments were reported to be slightly smaller than that of the free ion value due to the crystal "eld (12). For a comparably similar perovskite PrScO , where the magnetic ions are only in the lanthanide site, this value is calculated as 3.27 /Pr (12).…”

An Investigation of the Magnetic Properties of Sm1−xTiO3forx=0.03, 0.05, and 0.10: Magnetic Structure Determination of Sm0.97TiO3by Short-Wavelength Neutron Diffraction on Single Crystals

“…A remarkable variation in the magnetic properties as a function of decreasing rare earth radius exists, ranging from antiferromagnetic Ti-Ti coupling for R"La, Ce, Pr, and Nd to ferromagnetic Ti-Ti coupling for R"Gd-Lu, Y (5)(6)(7)(8). In spite of the interesting position of Sm in the series, evidence for any type of magnetic ordering for the R"Sm compound had remained elusive (9).…”
