Siemens Award: Recognition of the Entire Discipline of Spintronics

Abstract

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.

Making EuO multiferroic by epitaxial strain engineering

Abstract

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.

Young Czech physicist breaks with conventional wisdom inherited from George Ohm, Edwin Hall and Louis Néel

Abstract

In a paper published in Science Advances, Libor Šmejkal with his colleagues from the Institute of Physics of the Czech Academy of Sciences in Prague reports the discovery of a Hall effect in an antiferromagnet. It is another extraordinary work by an exceptional Czech talent who as a fresh PhD graduate already enjoys the reputation of an internationally leading figure in his field.

Realization of the building block of a Hund’s metal

Abstract

The research community is intensively searching for new materials, hopefully showing superconductivity under ambient conditions, which would solve many of the most pressing problems of the current era of information technology. For a target-oriented search of such materials, the electron properties of the basic constituents of Hund’s metals need to be understood in detail, and this requirement was lacking so far.
