摘要
Influence of the strontium concentration on the ferroelectric properties of SBN crystals in a wide temperature range was studied. It is shown that at room temperature in SBN crystals without relaxor properties the value of the pyroelectric coefficient is smaller than that of relaxor-like SBN. The relaxor properties are at the origin of occurrence in these crystals of an inversion layer and unstable polarization state.
