Electrical and Magnetic Properties of the Pr2/3 + xTiO3 ± yPerovskite Phase

The thermoelectric power, electrical resistivity, and magnetic susceptibility of the praseodymium titanium bronze phase Pr2/3 + xTiO3 ± ywere measured for compositions in the range 0 ≤ x≤ 1/3. The conductivity of the bronze was found to exhibit metallic behavior between 77 and 450 K. The transport data were used to evaluate the electron mobility and Fermi energy. In the range 77–300 K, the magnetic susceptibility of Pr2/3 + xTiO3 ± yconsists two contributions—those from Pr3+(a strong function of temperature) and Ti3+(a weak function of temperature).
