From: Novel dielectric anomalies due to spin-chains above and below Néel temperature in Ca3Co2O6

Polarization as a function of temperature (obtained as explained in the text) for Ca3Co2O6.
Inset (a) shows the low temperature data in an expanded form. The inset (b) shows polarization (plotted in the form of ΔP = [P(H)-P(0)/P(0)] as a function of magnetic field at 2.6 K.
