Abstract

Here we report on dielectric studies on Ni3TeO6. We confirm the spin-driven pyroelectric transition at the Neel temperature (T-N) of similar to 52.5 K. The measurement of single crystalline and polycrystalline samples excludes a ferroelectric nature of the transition at TN in this compound. The excellent pyroelectric properties without any intrinsic ferroelectric hysteresis make Ni3TeO6 appropriate for applications in future devices. [GRAPHICS] Pyroelectric measurements on our Ni3TeO6 single crystals. The polarization that appears on cooling through TN can not be inverted by opposite poling fields (applied when cooling from above TN to base temperature). (C) 2017 WILEY-VCH Verlag GmbH & Co.
