Imagine flipping a dial to make a material behave like a perfect conductor, a complete blocker, or something intriguingly in-between that could help us to better understand the puzzling quantum world. That’s the idea behind a new study in Physical Review Letters, co-authored by FZU researcher Filip Křížek within an international collaboration.
It is with deep sadness that we announce that on Saturday, August 23rd, our friend and colleague, physicist Dr. Karel Výborný, suddenly and tragically passed away. Karel died in an accident in the mountains he loved. He was 47 years old and is survived by his wife and two children.
Czech physicist Tomáš Jungwirth is one of the most important figures in contemporary world science thanks to his groundbreaking research in the field of spintronics. In 2024, he gained awards on several prestigious platforms, confirming his key contribution to scientific knowledge.
The family of magnetic materials has been traditionally divided into the ferromagnetic branch known for several millennia and the antiferromagnetic branch known for nearly a century. Researchers from the Institute of Physics of the Czech Academy of Sciences have recently made a discovery of a new branch of the magnetic family, termed altermagnetic.
The Česká hlava (Czech Head) National Government Award has been presented by the Minister for Science, Research and Innovation to Tomáš Jungwirth from the Institute of Physics of the Czech Academy of Sciences. He received the most prestigious scientific award for his contribution to spintronics research. The ceremony of the 23rd edition of the competition brought recognition also to David Vojna, who received the Doctorandus Award for Technical Sciences.
On 18th and 19th November 2024, a traditional workshop organized by the Department of Spintronics and Nanoelectronics of FZU took place in Villa Lanna. The program was divided into thematic lecture blocks encompassing not only the recently discovered family of altermagnetic materials but also superconductivity and terahertz and antiferromagnetic spintronics from both theoretical and experimental points of view.
A double interview with Helena Reichlova and Barbora Špačková, who have succeeded in tough competition and both won five-year funding for their own Dioscuri centres. They describe, for example, the role they believe social media play in research careers. And they also explain what guides their selection of new collaborators.
May 1st 2024 marked the 20th anniversary of the Czech Republic joining the European Union (EU). The past 20 years have profoundly changed the Czech research landscape, German-Czech research cooperation and the European Research Area. “Science has greatly benefitted from the possibilities that Europe offers during the last decades. Mobility is a striking example, funding opportunities are another,” says Max Planck President Patrick Cramer at the opening ceremony for the first three Dioscuri Centres in the Czech Republic on 17 May 2024.
Theoretical interpretation often steps into the spotlight first once breakthrough experiments have been finished. A much more exciting situation, especially in the realm of spectral properties of magnetic materials, is when a theoretical prediction persuades researchers to undertake a specific measurement approach, and subsequently, the collected data align precisely with the prediction. Research that resulted in a paper published last week in Physical Review Letters, where an international team reported that the way light is absorbed by a magnetic substance varies according to its state of polarization, followed just this less common line of development.
The research in TERAFIT project will focus on the development of applications that are essential for the Internet of Things and the Big Data economy. The aim is to achieve breakthroughs towards a new generation of information technologies – the three research objectives of the project focus on interconnected breakthroughs that will lead to substantial savings on energy, space and time scales.
"A scientific discovery has no merit unless it can be explained to a barmaid.” This quote by Nobel laureate Ernest Rutherford could be applied to the recent achievements of Libor Šmejkal. He was selected from hundreds of nominated scientists to be awarded the Breakthrough Scientific Discovery of the Year 2023 title in the Falling Walls competition for his theoretical work on altermagnetism and non-dissipative nanoelectronics. He was able to explain his discoveries to the general public by comparing a new form of magnetism to the dance of swans. His scientific career illustrates the importance of the role of teachers and mentors and symbolises a commitment to discovery and contribution to scientific knowledge.
In an article published in Nature an international team of scientists breaks down the traditional idea of dividing magnetism into two branches – the ferromagnetic one, known for several millennia, and the antiferromagnetic, discovered about a century ago. Researchers have now succeeded in directly experimentally demonstrating a third altermagnetic branch theoretically predicted by researchers in Prague and Mainz several years ago.
