Welcome to Stirin!

The physics and application prospects of relaxor ferroelectrics are subject of continuously growing interest. The need for a world-wide discussion forum focused on this subject has led to several ad-hoc meetings organized in the past. The recent positive and useful experience of participants of the International Workshop on Structure–Property Relations in Relaxor Ferroelectrics organized in Xi'an, China, 2011; the Workshop on Relaxor Ferroelectrics organized in Schloss Edesheim, Germany, 2012; and the International Workshop on Relaxor Ferroelectrics held in St. Petersburg, 2013 has motivated the advisory board of the last one to establish a regular biennial chain of focused workshops as a platform aimed to enhance the communication, exchange and collaboration among the researchers working in relaxor ferroelectric physics and materials science.

The event was held in Stirin, Czech Republic, on 12–16 October 2014. The chateau surrounded by a well-kept park provided a great venue for the Workshop, period accommodation as well as fascinating landscape. The single-session workshop program involved 51 oral and 26 poster presentations.

We would like to thank all the participants for outstanding talks and poster presentations, as well as for creating a great audience.

Ad Hoc Workshop for users of the crystallographic software Jana2006

There was a satellite workshop on Jana2006:

16–17 October: The 23rd Ad Hoc Workshop on Jana2006, Basics

Registration for the Jana2006 Workshop was made through the e-mail . There was no registration fee, lunches and coffee were paid on-site. There was no pre-arranged accommodation. The limit was 16–20 participants, each participant was expected to bring his/her own Windows-based laptop computer. We provided a limited number of laptops for the participants.



The Hotel Chateau Stirin, Ringhofferova 711, 251 68 Kamenice – Stirin, is located 25 km southeast from the Prague city centre. The chateau and its facilities are nestled in a peaceful countryside among extensive forests and numerous ponds. The site includes an English style chateau park.

Stirin Chateau


Documentation of the village and fortress of Stirin under the rule of Chval of Stirin dates back to the 14th century. Starting in 1751, the manor belonged to the Salm-Reifersheid family, who reconstructed the complex into a Late Baroque representational seat with a chapel. In 1822, Prince Rohan acquired the manor; however, he sold it to Count Nostitz-Rhieneck in 1831. A significant turning point in the development of the Stirin chateau and its surroundings occurred in 1870, when the manor, including the chateau was bought by Baron Frantisek Ringhoffer, under whose reign the architect Stibral carried out further reconstruction. The Ringhoffer family owned the chateau and other real estate until 1945, when the state took over all the buildings and the adjacent landscaped nature park. Between 1985 and 2007, the chateau and park were strikingly renovated upon the initiative of Vaclav Hruby with the goal of creating hotel, conference and cultural facilities serving for sports and relaxation. Since 1995, the chateau has been the property of the Ministry of Foreign Affairs of the Czech Republic.

Chateau Stirin


The conference venue is not far from the capital but we strongly encourage all participants to arrange their accommodation directly in Hotel Stirin facilities.

High-standard accommodation is offered in five buildings of Hotel Chateau Stirin:

City of Prague

Prague, the capital of the Czech Republic, is well known for its historical monuments, classical architecture and rich cultural heritage that continues today in many theaters, concert halls, opera houses and galleries. Come and discover this wonderful city and walk in the footsteps not only of Franz Kafka and Antonin Dvorak but also of Tycho de Brahe, Johannes Kepler, Bernard Bolzano, Christian Doppler, Albert Einstein, Jaroslav Heyrovsky, Vladimir Prelog and others.

Historical centre of Prague

Prague has 1.3 million inhabitants living on approximately 500 square kilometers. The historical city center is a designated UNESCO World Cultural and Natural Heritage area which stretches over more than 8 square kilometers. Charles University in Prague, founded in 1348, is the oldest university in Central Europe.

The dominant feature of the city is Prague Castle with its gothic St. Vitus Cathedral. The castle, formerly the seat of Czech kings since 1087, became the seat of the president in 1918. The Lesser Town below the castle boasts a profusion of intimate corners and character restaurants blended with splendid aristocratic palaces and charming gardens. The 14th century Charles Bridge, the most remarkable promenade site in Prague, connects Lesser Town with the Old Town, amazing network of twisting medieval lanes. The Old Town City Hall in the Old Town Square houses the oldest working Astronomical Clock in the world (1410). At every hour, a presentation of four figures and statues of 12 Apostles starts. Between the Old Town Square and the river bank, remains of unique 13th century Jewish Town offer mysterious spiritual atmosphere. Due to hilly landscape over double-bent river valley, the elevated sites such as the Castle offer magnificent views over the city's “one hundred spires”.

Getting to Prague

Vaclav Havel Airport Prague handles flights of most European carriers, including low-cost ones, as well as some overseas flights. To find the most appropriate flight without the need of visiting individual carrier websites, you may try a global travel search site such as http://www.skyscanner.net/.

Getting to Stirin

Stirin is located approximately 40 km from the airport. For detailed information, please see the How to get there section.

Details for poster presentations

The ideal format is A0 portrait as the poster boards are 100 cm wide and 120 cm high. Please do not use self-adhesive tapes or Velcro which will not work. Pins will be available on site.

There will be no dedicated poster session. All posters will be displayed throughout the duration of the Workshop. We recommend mounting all the posters on Monday after lunch. All the posters should be removed on Thursday before 11:00.

Invited and oral presentations

The time dedicated to your talk is indicated in the online program. Please make sure to include enough time for discussion (15–20%).

A conference laptop with Windows 7 operating system will be available for presentations. The following presentation file formats will be supported:

If you intend to use the conference laptop (preferred option), please provide your presentation file on a USB flash disk at least 10 min before the session starts.
