Preparation specifics and properties of AMn3V4O12 (А = Ca, Ce, and Sm) high-pressure phases

Perovskite-like phases AMn 3 V 4 O 12 (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 3 ¯ , Z = 2) was determined, and unit cell parameters were calculated: for CaMn 3 V 4 O 12 : а = 7.40824(3) Å, f...

Description
Summary:Perovskite-like phases AMn 3 V 4 O 12 (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 3 ¯ , Z = 2) was determined, and unit cell parameters were calculated: for CaMn 3 V 4 O 12 : а = 7.40824(3) Å, for SmMn 3 V 4 O 12 : а = 7.45280(8) Å, and for CeMn 3 V 4 O 12 : а = 7.46965(4) Å. The temperature-dependent electrical resistivity (10–300 K) and magnetic susceptibility (2–300 K) of the prepared phases were studied.
