New high-pressure perovskite-like phases ACu$_{3}$V$_{4}$O$_{12}$ (A-Sm, Gd, Tb, Dy, Er and Tm): synthesis and electrical properties*

The aim of this work was to investigate the effect of high pressures on the electrical properties of the new high-pressure perovskite-like phases ACu$_{3}$V$_{4}$O$_{12}$ (A-Sm, Gd, Tb, Dy, Er and Tm). The X-ray and microstructural studies of the synthesized by barothermal compression compounds were carried out. The electrical properties of the compounds were studied in the wide ranges of frequencies of the electric field, temperatures and pressures.
