Multicaloric effect: An outlook

We describe how mechanical strain is able to control the flow of heat on a graphene sheet, since this material can either absorb or expel heat from/to a thermal reservoir, depending on the strain energy. In a similar fashion as the magneto- and electro-caloric effects, the present case considers the fact that a mechanical strain produces a pseudo-magnetic field that, on its turn, is responsible for the barocaloric effect. This result pushes graphene to the list of multicaloric materials.

The terms "multicaloric effect" and "multicaloric" are relatively new concepts and combine the phenomena and materials associated with the coexistence of conventional caloric effects under the action of external forces of various nature (magnetic field, electric field, mechanical action). Nowadays, caloric materials remain in the focus of attention of researchers, and approaches based on the use of the multicaloric effect are considered as one of the ways to improve the efficiency of conventional solid-state cooling systems. Of particular interest from a fundamental point of view are the cross effects observed under the combined external stimulus, as well as the nature of the relationship between magnetic, electrical, thermophysical properties and structure under such actions. In this review, the theoretical foundations of the multicaloric effect are considered and an attempt is made to systematize multicaloric materials. Applied aspects of multicalorics are considered separately, and various experimental approaches to the study of their properties are presented. The presented review will be of interest to a wide range of specialists involved in the study of materials with caloric effects (magnetocaloric, electrocaloric, mechanocaloric), as well as those who are searching for new functional materials. Keywords: magnetocaloric effect, electrocaloric effect, elastocaloric effect, barocaloric effect, multicaloric effect, multiferroics, multicalorics, magnetoelectric composites.

“…Одним из современных и активно исследуемых в последние годы направлений в физике конденсированного состояния является подход, основанный на идее использования парных КЭ. Основанный на наблюдении хотя бы двух из известных КЭ подход к исследованию термодинамических свойств материалов получил объединительный термин " мультикалорический" и стал рассматриваться в качестве перспективной основы для улучшения эффективности энергетических систем, основанных на одиночных калорических эффектах [6][7][8].…”
