Pyroelectric studies on ferroelectric lithium vanadate doped with ferric oxide

Abstract

Abstract The effect of ferric oxide on pyroelectric properties of lithium vanadate has been investigated in the temperature range covering their transition points. The pyroelectric current and the coefficients of undoped LiVO3 and doped with Fe2O3, have shown sharp peak at their Curie temperatures. It was found that the pyroelectric current and coefficients increase with the increase of ferric oxide concentration. The Curie temperatures of lithium vanadate decreased with the increase of dopant concentration.
