Metal–insulator transitions of SrTi1−xVxO3 solid solution system

摘要: Abstract Compounds in the solid solution SrTi1−xVxO3 system were synthesized and studied for their conductivity magnetic properties. The data show that compounds with high vanadium content (x>0.7) are metallic low x semiconductors various conduction mechanisms depending on x. x=0.7 compound shows a temperature dependent metal–insulator transition at 120 K. Compared literature same system, present can be explained clustering of atoms forms discrete d-bands. A model involves localized states or bands is proposed to explain composition properties data.
