The set-up allows one to perform on-line Mössbauer measurements (implantation) under the various magnetic fields and in a broad temperature range. This is a collaborative project with CERN/ISOLDE Emission Mössbauer Collaboration.

The project aims at the development and construction of a new unique Mössbauer magnetometer at ISOLDE/CERN for the investigation of innovative magnetic materials for the energy turnaround. The unique apparatus will allow the simultaneous investigation of magnetic materials with magnetometer and Mössbauer spectroscopy. This will enable investigations for the atomistic understanding of magnetic materials, which will allow the design of new innovative magnetic materials with a hysteresis design. The atomic resolution of the hyperfine probes at ISOLDE, combined with the macroscopic results of the magnetometer, will allow unique possibilities for the hysteresis design of innovative magnetic materials for the energy revolution. New magnetic materials are urgently needed for the energy revolution. In addition to the replacement of rare and critical elements, new approaches and production methods (additive manufacturing) of such materials must be explored and implemented in industry. For a successful implementation, a fundamental understanding of the atomic interactions in such magnetic materials and their effect on hysteresis must be investigated. ISOLDE offers an ideal solution to this problem, since all materials can be investigated by implanting the appropriate nuclear spies. This is, however, so far prevented by the fact that the corresponding equipment is not available at ISOLDE. The planned project is intended to remedy this situation and thus enable fundamental investigations and ultimately provide the industry with valuable starting points for new materials and their production.
