Lead magnesium niobate (PMnN) is a ceramic perovskite material that is part of the family of lead-based ferroelectric ceramics. Its chemical formula is often represented as \( \text{Pb(Mg}_1/3\text{Nb}_2/3)\text{O}_3 \). PMnN is known for its high piezoelectric and dielectric properties, making it a material of interest in various applications, particularly in electronics and materials science.
