Berry phase effects on electronic properties (2009, background): “…include flexoelectricity where a finite polarization is produced by a strain gradient (Tagantsev, 1986, 1991), and multiferroic materials where the magnetic ordering varies in space and induces a polarization (Cheong and Mostovoy, 2007; Fiebig et al., 2002; Hur et al., 2004; Kimura et al., 2003).”
