Abstract

The transport and magnetic properties of a series of Nd1-xCaxTiO3 perovskites where 0x0.8 were investigated. The transition from a Mott-Hubbard insulator (NdTiO3) with a 3d1 configuration to a metallic state was observed to take place near x=0.15. Low-field susceptibility and remanent-moment measurements suggest that Nd1-xCaxTiO3 orders antiferromagnetically in the composition region 0x0.15. The metallic Nd1-xCaxTiO3 compounds behave as Fermi-liquid systems where the effective mass increases as the metal-insulator boundary (x0.15) is approached.
