Abstract

The establishment of this 11 T superconducting magnet with He3 insert device at the EMA beamline of the new Brazilian light source, Sirius, is part of the strategy for develop state of the art experimental stations for the study of emerging phenomena in materials under extreme conditions of pressure, temperature and magnetic field, combining Synchrotron techniques such as X-ray diffraction (XRD) and X- ray absorption spectroscopy (XAS) with transport techniques such as resistivity and Hall measurements. The possibility of applying high magnetic fields,11T, will allow the x-ray magnetic circular dichroism technique (XMCD) to be applied in materials with a week magnetic response, as antiferromagnetic materials. In addition, with this new equipment we will be able to perform quantum oscillations measurements as a function of the pressure to study the evolution of the Fermi surface in topological materials. In summary, this new equipment will expand the possibilities of studying the electronic, magnetic, structural and transport properties of different types of materials (ferromagnetic, antiferromagnetic, superconductors, heavy fermions, among others) under high pressure (up to 300 GPa), high magnetic field (up to 11T) and low temperatures (down to 300mK), and will be crucial for the development of materials science research in Brazil.
