(a) Crystallographic and magnetic structures of antiferromagnetically ordered Ni3TeO6. Inset: As-grown ~100-μm-thick Ni3TeO6 single crystal. Scale bar=0.5 mm. (b) Temperature dependence of DC magnetic susceptibility χ(T) and 1/χ(T) parallel (black) and perpendicular (grey) to the c axis of NTO-a at μ H=0.2 T. (c) Temperature dependence of dielectric constant ɛ(T) of NTO-b along the c axis at various magnetic fields applied along the c axis.
