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

Electrical resistivities were measured as a function of temperature in the range below 300 K for single-crystal samples of PrTiO3 and NdTiO3. Both materials are semiconductors with room temperature activation energies of 0.03 to 0.04 eV. Magnetic susceptibilities for PrTiO3 and NdTiO3 follow the Curie-Weiss law at high temperatures with Cm = 1.73(3) and Θc = −49(3) K (PrTiO3), and Cm = 1.77(3), Θc = −35(3) K (NdTiO3). For PrScO3 and NdScO3, …
