Fig. 2: Magnetically induced polarization in magnetic fields.

a Temperature dependence of relative dielectric constant at μ₀H = 0 T. b Temperature dependence of the electric polarization at μ₀H = 0 T measured on warming runs. Before the measurement, we cooled the sample from 450 K to 320 K in electric fields E_c = ±435 kV m⁻¹. c Temperature dependence of the electric polarization measured on warming runs in the absence of any external field after cooling the sample down to 320 K applying magnetic fields ∣μ₀H∣ = 10 T with various directions.
