Libor Šmejkal from the Institute of Physics of the Czech Academy of Sciences has won the second place in the “Best Dissertation Thesis” category in this year’s Werner von Siemens Award. Libor won the award for the thesis entitled “Topology band theory of relativistic spintronics in antiferromagnets” supervised by professor Tomáš Jungwirth.
Researchers from the Institute of Physics of the Czech Academy of Sciences and Charles University have just published in Nature Electronics their new experiment in which they succeeded to write information into an antiferromagnet by femtosecond-laser pulses.
Magnetoelectric multiferroic are materials where the ferroelectric and magnetic ordering can coexist and be mutually coupled. This phenomenon is called magnetoelectric coupling and can in principle be used to improve magnetoelectric memories or other electric-field-controlled spintronic or magnonic devices. Unfortunately, there are a relatively small number of single-phase multiferroics in nature and their magnetoelectric coupling is lower than needed for many applications.
The recently deceased Ing. Ludvík Smrčka, DrSc., an outstanding researcher and a friend, as remembered by four of his colleagues.
The new discovery not only allows a thousand times faster data storing, but it may also find applications in AI and artificial neural networks.
In its time it was one of the highest performance supercomputers in the Czech republic. The Dorje cluster solved many issues in the field of solid-state physics.
