Study on multicaloric effect of CuO induced multiferroic

One of the induced multiferroic materials, CuO has the magnetic as well as ferroelectric phase transition at same temperature (T-N1 similar to 213 K, T-C and T-N2 similar to 230 K). These type of materials can show two types of entropy; magnetic field induced entropy (Magnetocaloric Effect) as well as electeric field induced entropy (Electrocaloric Effect). The presence of both type of entropy may be called Multicaloric Entropy (M. Vopson, Solid State Commun. 152, 2067 (2012) and Meng et al., Phys. Lett. A 377, 567 (2013)). We observed that Multicaloric Entropy in the induced multiferroic materials also depends on the magnetoelectric interaction (gamma). Therofore, this numerical attempt to calculate the entropy of CuO may be useful for the future electromagnetic based refrigerator technology. (C) 2014 AIP Publishing LLC.
