✦ Synopsis
IN HONOR OF PROFESSOR PAUL HAGENMULLER ON THE OCCASION OF HIS 80TH BIRTHDAY
Some solid state chemistry aspects are investigated in relaxor ferroelectrics of both perovskite and tetragonal tungsten bronze (TTB) structure. Various issues regarding composition, cationic charge, electronic con5guration, and structure are discussed. The relaxor behavior appears when two di4erent cations occupy the same crystallographic site. One of the cations in the octahedral site has to be ferroelectrically active. The relaxor e4ect is correlated to cationic distribution disorder in the same site, depending on composition and structure (perovskite or TTB).
