Description
Summary:(ProQuest: ... denotes formulae and/or non-USASCII text omitted; see image) AMn3V4O12 (A = Ca, Ce, and Sm) compounds with a perovskite structure are synthesized at high pressures and temperatures. The crystalline structure of these compounds (space group ... Z = 2) is determined via X-ray analysis. If ions in the A sublattice are changed in the order Ca2+-Sm3+-Ce3+, the valence is redistributed from Ca2+Mn 3 2+ V 4 4+ O12 to Sm3+Mn 3 2+ V 4 3.75+ O12, and to Ce3+Mn 3 2+ V 4 3.75+ O12. The temperature dependences of the electrical resistivity are studied.
