    The third-order E2H2 magnetoelectric response of EuTiO3 changes sign under magnetic bias and shows a large anomaly at the antiferromagnetic-paramagnetic phasou boundary below TN=5.3 K. It is atributed to critical fluctuations of the antiferromagnetic order parameter reinforced by quantum paraelectric polar correlations.
