На примере слоистой структуры состава цирконат-титанат свинца – феррит кобальта показана возможность увеличения калорических эффектов в магнитострикционно-сегнетоэлектрических слоистых структурах. Приложение к магнитострикционно-сегнетоэлектрической структуре внешних магнитного и электрического полей ведет к индуцированию эластокалорического эффекта и к росту мультикалорического эффекта.</p></abstract><trans-abstract xml:lang="en"><p>A method for calculating the multicaloric effect in magnetostrictive-ferroelectric layered structures is considered. The multicaloric effect is a superposition of magnetocaloric, electrocaloric and elastocaloric ones. As an example of magnetostrictive-ferroelectric layered structures, the layered structure of lead zirconate titanate and cobalt ferrite provides the possibility of increasing the caloric effects. The application of external magnetic and electric fields to the magnetostriction-ferroelectric structure leads to the inducing the elastocaloric effect and thus to the increased multicaloric effect.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>математическое моделирование</kwd><kwd>электрокалорический эффект</kwd><kwd>магнитокалорический эффект</kwd><kwd>барокалорический эффект</kwd><kwd>мультиферроик</kwd></kwd-group><kwd-group xml:lang="en"><kwd>mathematical modeling</kwd><kwd>electrocaloric effect</kwd><kwd>magnetocaloric effect</kwd><kwd>barocaloric effect</kwd><kwd>multiferroic</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование выполнено за счет гранта Российского научного фонда № 22- 21-20119, https://rscf.ru/project/ 22-21-20119/.</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Electrocaloric Materials: New Generation of Coolers.
