Materials characterization in highest magnetic fields

In this presentation, I will discuss the characterization of materials in extremely high magnetic fields, reaching up to nearly 100 T. The first part of the talk will address the technical challenges associated with generating such high magnetic fields. Within the ReMade@ARI project, two high-field facilities are participating: the High Field Magnet Laboratory (HFML) in Nijmegen, capable of generating static fields up to about 38 T, and the Dresden High Magnetic Field Laboratory (HLD), which can provide pulsed fields up to about 95 T. I will provide an overview of the experimental techniques available at these facilities for the characterization of new materials. In the final part of the presentation, I will discuss methods for characterizing materials with potential applications in cooling technology. Specifically, I will focus on measurements of the magnetocaloric effect, which can be used to investigate the adiabatic temperature change in a material under high magnetic fields. These experiments are instrumental in identifying materials suitable for use in cooling devices.
