摘要
A perspective on computational studies of ferroelectrics and multiferroics is given that emphasises what has yet to be done,along with some subtleties in previously studied systems.Beginning with the extensive data-mining studies of Abrahams and more recently,Rabe,a survey is given of magnetostrictive effects in antiferromagnetic antiferroelectrics(after Toledano and Toledano),which has an nonmagnetic analogy in the antiferroelectric phase of tris-sarcosine calcium chloride and a reminder of the unusual spin–phonon coupling of Holden et al.in systems such as KCoF3 and EuTiO3.Attention is also paid to field-temperature phase diagrams,finite non-periodic boundary conditions,and processing-dependent structures.
