Fig. 2: Dielectric and magnetoelectric (ME) anomalies in the Sr2IrO4/SrTiO3 superlattices.
From: Magnetoelectric phase transition driven by interfacial-engineered Dzyaloshinskii-Moriya interaction
a Temperature-dependent dielectric constant measured along the z-direction for series of SIO/STO superlattices. b ME response as a function of temperature by the standard dynamic measurement. The maximum ME output in these superlattices occurs when a dielectric anomaly appears.
