“…This would be undoubtedly connected with the disorder created on the A site of BaTiO 3 as a consequence of La/Na/Eu substitution. Comparing our data to published results by Kchikech and Maglione [34], Lagos et al [35] and Kim et al [36] on the tetragonal BaTiO 3 , we are able to make the following normal mode assignments. For xp0.1, the A 1 transverse optical (TO) modes are observed as broad lines at 250 and 522 cm À1 .…”

“…The A 1 longitudinal optical (LO) modes can be identified at 725 cm À1 . The 307 cm À1 peak can be assigned to the E(TO+LO)+B 1 modes [35]. This mode appears only on entering the tetragonal phase and can be therefore considered as the signature of the tetragonal to cubic phase transition.…”

“…The surface topography and PFM images of a polished sample embedded in epoxy is shown in Supplementary Fig. 18, with clearly visible variation of DART PFM contrast at the grain boundaries, some grains show clearly visible domain structures, highly reminiscent of domain structures for materials such as BaTiO 3 46, 47 .…”

Double corundum-related polar magnets are promising materials for multiferroic and magnetoelectric applications in spintronics. However, their design and synthesis is a challenge, and magnetoelectric coupling has only been observed in Ni3TeO6 among the known double corundum compounds to date. Here we address the high-pressure synthesis of a new polar and antiferromagnetic corundum derivative Mn2MnWO6, which adopts the Ni3TeO6-type structure with low temperature first-order field-induced metamagnetic phase transitions (T N = 58 K) and high spontaneous polarization (~ 63.3 μC·cm−2). The magnetostriction-polarization coupling in Mn2MnWO6 is evidenced by second harmonic generation effect, and corroborated by magnetic-field-dependent pyroresponse behavior, which together with the magnetic-field-dependent polarization and dielectric measurements, qualitatively indicate magnetoelectric coupling. Piezoresponse force microscopy imaging and spectroscopy studies on Mn2MnWO6 show switchable polarization, which motivates further exploration on magnetoelectric effect in single crystal/thin film specimens.
