Forskning: A New Level of Magnetic Saturation
An international group of astronomers including Dr. Oleg Kochukhov from the Department of Physics and Astronomy at Uppsala University has detected unexpectedly strong magnetic fields on the surface of a few fast rotating M dwarf stars.
The press release from Georg-August University says:
"For a long time it was thought that the dynamo in these stars saturates with a maximum magnetic field strength of about four kilogauss (kG) if a star rotates faster than a particular rotation rate. Using accurate observations and up-to-date models, the researchers discovered that some fully convective M dwarfs generate even stronger fields of up to about seven kG. The results were published in Nature Astronomy on 24 July 2017."

Research Funding: Grants for renewable-energy research
The Swedish Research Council and the Swedish Energy Agency are collaborating in an initiative to provide project grants for energy-oriented basic research. Which projects to fund in the 2017 call for applications has now been decided. Uppsala University is receiving grants for four projects.
Research: On the hunt for new and peculiar superconductors
Annica Black-Schaffer wants to understand unconventional superconductors. The fact that she recently received the prestigious ERC Starting Grant and is a former recipient of grants from the Knut and Alice Wallenberg Foundation is a testament to the interest in her research. One beckoning application is tomorrow’s supercomputers.
Research: Measuring magnetism in 3D
A team of researchers from Uppsala University, China and Germany have substantially extended the possibilities of an experimental technique called EMCD, that is used for measuring magnetism in materials. The results were published in Nature Communications on May 15 2017.

Press release: Magnetic order in a two-dimensional molecular chessboard
Achieving magnetic order in low-dimensional systems consisting of only one or two dimensions has been a research goal for some time. In a new study published in the journal Nature Communications, Uppsala researchers show that magnetic order can be created in a two-dimensional chessboard lattice consisting of organometallic molecules that are only one atomic layer thick.
Education: New study program for people newly arrived in Sweden
In collaboration with the municipality of Uppsala and the Department of Scandinavian languages, the Department of Physics and Astronomy is organising a preparatory year for those newly arrived in Uppsala who would like to study at the university.
