- Proving first time ever the origin of the high electricaloric anisotropy effect in a lead‐free relaxor ferroelectric material; Sr(0.75)Ba(0.25)Nb(2)O(6), by a theoretical model validated experimentally The model show the two types of contributions from the polar nanodomains and the polar surrounding and describes their energy threshold for every structural phase change over temperature and applied DC field. The paper has been acknowledge worldwide as an important contribution to future cost‐ and energy‐efficient cooling devices by producing low‐cost grain‐oriented ceramics. As a result it has been described in both plenary and keynote speech in international conferences.
