Here we report on dielectric studies on Ni 3 TeO 6 . We confirm the spin‐driven pyroelectric transition at the Néel temperature ( T N ) of ∼52.5 K. The measurement of single crystalline and polycrystalline samples excludes a ferroelectric nature of the transition at T N in this compound. The excellent pyroelectric properties without any intrinsic ferroelectric hysteresis make Ni 3 TeO 6 appropriate for applications in future devices. Pyroelectric measurements on our Ni 3 TeO 6 single crystals. The polarization that appears on cooling through T N can not be inverted by opposite poling fields (applied when cooling from above T N to base temperature).
