摘要: Perovskite-like phases AMn3V4O12 (A = Ca, Ce, and Sm) were prepared under borothermic conditions (p 7.0–9.0 GPa, T 700–1100°C). Their X-ray diffraction structure (space group Im\(\bar 3\) , Z 2) was determined, unit cell parameters calculated: for CaMn3V4O12: а 7.40824(3) A, SmMn3V4O12: 7.45280(8) CeMn3V4O12: 7.46965(4) A. The temperature-dependent electrical resistivity (10–300 K) magnetic susceptibility (2–300 of the studied.
