DOI: 10.1103/physrevb.101.174108
Abstract: Short-range ordered polar nanoregions are key to the giant electromechanical properties exhibited by relaxorferroelectrics. Stabilization of the long-range ferroelectric order in relaxor systems has typically been achievedby applying external fields. In this work, spontaneous (zero-field)… read more here.

DOI: 10.1126/sciadv.aau7725
Abstract: NMR captures mobile spin solitons deconfined from a charge-lattice–coupled nonmagnetic ferroelectric order. Topological defects have been explored in different fields ranging from condensed matter physics and particle physics to cosmology. In condensed matter, strong coupling… read more here.
