In the present work, thermodynamics analysis and phase field simulations were conducted to demonstrate the mechanical compression-induced two types of pseudo-first-order phase transition, which could occur at a temperature below the Curie temperature. Thus, in one material there may coexist ultrahigh positive and negative electrocaloric effects, which are associated with the two pseudo-first-order phase transitions and tunable by the magnitude of the compression. The mechanical compression-induced pseudo-first-order phase transition and the coexistence of positive and negative electrocaloric effects will facilitate the development of a novel technology to design and manufacture next generation of solid-state cooling devices.","descriptionType":"Abstract"}],"geoLocations":[],"fundingReferences":[],"xml":"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","url":"https://figshare.com/articles/dataset/Pseudo_first_order_phase_transition_for_ultrahigh_positive_negative_electrocaloric_effects_in_perovskite_ferroelectrics/1512316","contentUrl":null,"metadataVersion":1,"schemaVersion":"http://datacite.org/schema/kernel-4","source":"mds","isActive":true,"state":"findable","reason":null,"viewCount":0,"viewsOverTime":[],"downloadCount":0,"downloadsOverTime":[],"referenceCount":0,"citationCount":0,"citationsOverTime":[],"partCount":0,"partOfCount":0,"versionCount":0,"versionOfCount":0,"created":"2015-08-15T14:57:27.000Z","registered":"2015-08-15T14:57:29.000Z","published":"2015","updated":"2020-09-04T16:05:36.000Z"},"relationships":{"client":{"data":{"id":"figshare.ars","type":"clients"}},"provider":{"data":{"id":"otjm","type":"providers"}},"media":{"data":{"id":"10.6084/m9.figshare.1512316","type":"media"}},"references":{"data":[]},"citations":{"data":[]},"parts":{"data":[]},"partOf":{"data":[]},"versions":{"data":[]},"versionOf":{"data":[]}}}}
