Electrocaloric and barocaloric effects in multicaloric BaTiO3


Ferroelectric materials typically show large changes of polarization and volume near first‑order phase transitions at the Curie temperature. These large changes can be exploited by driving the transitions using electric field or hydrostatic pressure, resulting in large electrocaloric or barocaloric effects. I will show that single‑crystal and polycrystalline samples of BaTiO3 display significant electrocaloric [1] and barocaloric [2] effects at the very sharp first-order ferroelectric phase transition near 400 K. Both caloric effects may be driven in full by relatively small external fields, thus yielding giant‑strength electrocaloric and barocaloric effects.


to the European Conference on Materials and Technologies for Sustainable Growth website.

ECo MaTech will be held in Bled (Slovenia) from 19th to 21st of September 2013.

Eco MaTech is the third edition of a conference that started in 2009. The aim of ECo MaTech is to gather representatives of academic and R&D institutions, industry, governmental agencies and civil society to:

- present their work, ideas and products, 
- increase fruitful exhanges between all the actors involved in sustainable growth technologies, 
- increase the networking with sustainable growth professionals, 
- establish a general discussion platform on sustainable growth.


The conference excursion will take you to the Alpine lake Bohinj (http://www.bohinj.si/en) and waterfall Savica (http://www.burger.si/Slapovi/Bohinj/Savica/uvod_ENG.html).
A farewell party will follow the lake trip by a boat. Comfortable shoes are recommended.

Only cash is exepted for on-site payment.

The poster panels are 1m wide and 2m high. The standrad A0 size posters are recommended (841mm:1189mm).
