All summerstudents will present their projects in a conference at HZB Campus Wannsee on thursday 18 September. The conference will start at 11:00 with four talks. The speakers have been elected by the summerstudents themselves. After lunch, the poster session starts. Every student has prepared a poster presenting her or his project, the context, the motivation and what has been achieved during the two months project in summer 2017. An award is given to the best poster along criteria such as communications skills, layout and design, and – of course – scientific achievement. 11.00-12.00 Oral Presentations 13.30 -15:30 Poster session 16.00 Presentation of the posterRead More →

An international team has examined pristine and slightly doped bismuth ferrite using experimental data obtained at HZB. The research shows the sequence of serial and trigger-type phase transitions, the temperature-dependent behavior of the order parameters, and the corresponding susceptibilities to external stimuli.  The material: Multiferroics are materials that exhibit multiple types of ferroic ordering, such as ferromagnetism and ferroelectricity, simultaneously. BiFeO3 (BFO) is the one of the rare multiferroics with a strong ferroelectric polarization, antiferromagnetism at room temperature as well as conduction and magnetotransport at domain walls. This makes it a candidate for a range of applications. The question: What are the underlying physical mechanismsRead More →
