Description

High magnetic fields are one of the most powerful tools to study, modify and control the different states of matter. Whereas commercial state-of-the-art superconducting magnets reach magnetic fields up to 23 T, higher fields are only available at a small number of specialized large-scale facilities. In Europe there are three major high field laboratories providing access for external users: HLD Dresden, HFML Nijmegen and LNCMI Grenoble-Toulouse, recently united in the European Magnetic Field Laboratory (EMFL). First, we will present the infrastructure of the Grenoble EMFL laboratory and its available experimental techniques. Second, we will focus on very high field solid-state nuclear magnetic resonance (NMR), a powerful microscopic method for investigating many problems in physics, chemistry and materials science. Recently, the options for NMR at Grenoble have been extended to very high magnetic fields (35 T) and frequencies (1.5 GHz), to very low temperatures (50 mK) as well as towards enhanced sensitivity and resolution (10 ppm). Using selected recent research projects we will demonstrate the potential of the available NMR instrumentation.
