Random electric field instabilities of relaxor ferroelectrics

Complex oxides: A random field state in a relaxor ferroelectric A microscopic model shows how compositional disorder in the form of quenched random electric fields acting in concert with dipolar interactions prohibit long-range ordering in relaxor ferroelectrics. Relaxor ferroelectrics are a class o...
