Coexistence of large positive and negative electrocaloric effects near room temperature in a Pb<sub>1−<i>x</i></sub>(Li,La)<sub><i>x</i></sub>ZrO<sub>3</sub>/Ca<sub>3</sub>Mn<sub>2</sub>O<sub>7</sub> heterojunction
The coexistence of positive and negative EC effects has been achieved in a PLLZ/CMO heterojunction near room temperature. At 303 K, a large positive Δ T of 33 K at 550 kV cm −1 and a large negative Δ T of −1.54 K at 140 kV cm −1 were obtained.
