Multiferroic and magnetoelectric materials have become increasingly popular due to the functionality they could provide in the sensing and medical fields. Single-phase multiferroic/magnetoelectric materials are incapable of large responses due to limitations imposed by various physical constraints. Multiphasic multiferroic/magnetoelectric materials are able to produce outputs many orders of magnitude higher than their physical counterparts as they rely on the coupling between the magnetostrictive and piezoelectric phases. These multilayered structures possess their own unique problems such as difficulty of deposition, and serial electrodes reducing dielectric performance. The effect of temperature on the magnetoelectric response of these multilayered multiferroics has not been thoroughly studied. The temperature dependence of the magnetodielectric and magnetoelectric properties of a CoFe₂O₄/PZT/CoFe₂O₄ trilayer laminate structure has been investigated. The experiments where performed using an AC magnetic field of 5 Oe, with increasing DC magnetic field biases. The measurements were taken at three temperature conditions: room temperature, the temperature decreasing slowly to 100 K, and then increasing the temperature up to room temperature again.
