Anisotropy of the Electrocaloric Effect in Lead‐Free Relaxor Ferroelectrics
Source abstract
Abstract
The highly anisotropic electrocaloric effect, evidenced by both direct measurements and a descriptive theoretical model in lead-free relaxor ferroelectric Sr0.75Ba0.25Nb2O6 single crystals, can be exploited by producing low-cost grain-oriented ceramics. Combined with the broad-temperature-range cooling regime provided by their polar nanoregions, these materials may be the key to future cost- and energy-efficient solid-state refrigeration.
