The metal-to-insulator (MI) transition in the Y1 \_xCa~TiO3 system is known to occur at x = 0.35. Furthermore, near this critical metallic region, electrical resistivity and magnetic susceptibility show a broad peak around 170 K and are accompanied by clear thermal hysteresis. This thermal hysteresi

✦ Synopsis
The metal-insulator transition in the Yl_xCaxTiO3 alloy system occurs about x = 0.35. Various physical property measurements suggest that this M-I transition cannot be understood as a simple change in the carrier number in the Hubbard band. In this paper, detailed magnetic property and electrical resistivity behaviours around M-I transition are discussed.

Various types of ground states in strongly correlated electron systems have been systematically investigated by means of NMR/NQR at low temperatures under high magnetic field and pressure. We focus on two well-known heavy-electron families, CeCu2X 2 (X = Si and Ge) (Ce(122)) and UM2AI 3 (M = Ni and
