STUDIES ON PREPARATION, STRUCTURE AND ELECTRICAL-PROPERTIES OF THE COMPLEX OXIDE SM3TI2O7

A new complex oxide Sm3Ti2O7 containing one bivalent and two trivalent samariumions in the molecule is prepared by the reduction of Sm2O3 and TiO2 with metallic Smat high temperature.Its structure and electrical properties were studies.The compoundSm3Ti2O7 belongs to monoclinic system.Its cell dimensions are α=3.969,b=3.907,c=20.460（?）;β=89.20°.Its electrical resistivity ρ is 7.4 Ω.cm.It changes fr..
