Science under extreme conditions

At HFML-FELIX, we generate intense infrared and Terahertz radiation with an unprecedented tuning range ánd the highest possible static magnetic fields. The opportunities we create with our exceptional infrastructure and instruments are world-wide unique.

Scientists can use the magnets and free-electron lasers to investigate materials with an unprecedented resolution and precision. This allows them to realize breakthroughs across a broad spectrum of disciplines.

Nowhere else you can find static high magnetic fields and free-electron lasers in one place


Using the powerful magnetic fields, Konstantin Novoselov and Andre Geim discovered the first 2D material graphene. A Nobel Prize-winning fundamental invention that has paved the way for new types of electronics.
The intense laser light plays an important role in mapping chemical processes and molecular structures, among other things. One example is research into new biomarkers that help physicians to identify various diseases.

Combination: new scientific field

Since 2019, scientist can place matter in the free-electron lasers and   simultaneously expose it to a high magnetic field.  Laser light runs from the laser cellar to the magnets through a 86-meter vacuum tube steered with 41 gold-plated mirrors. "It was a huge challenge to get it done," admits director Peter Christianen. However, it is clear that the combination of strong magnets and intense laserlight will yield interesting discoveries. “We are entering a whole new scientific field with the combination of our instruments", says director Britta Redlich. “You can actually change the properties of a material. That creates a huge number of possibilities. For example, we hope to discover the origin of superconductivity at high temperatures, which has been a mystery since the 1980s. The ultimate goal is to enable superconductivity at room temperature, so that electrical circuits use much less energy. "
