From: Highly nonlinear magnetoelectric effect in buckled-honeycomb antiferromagnetic Co4Ta2O9
Comparison of electric and magnetic properties. (a) Hb* dependence of Pa at T = 2 K. (b) Hb* dependence of the magnetodielectric effect along the a axis, MDa (%) = \(\frac{{\varepsilon^{\prime}\left( H \right) - \varepsilon^{\prime}\left( {0 {\text{T}}} \right)}}{{\varepsilon^{\prime}\left( {0 {\text{T}}} \right)}} \times 100\), measured with AC excitation of Ea = 1 V at f = 100 kHz and T = 2 K. (c) Hb* derivative of Mb* at 2 K.
