Magnetic materials span many important areas of condensed matter physics, from the study of fundamental collective quantum effects, through novel electronic properties in emerging materials and industrially important ferromagnets to potential future technologies such as spintronics. Common to all of these fields is that the most fundamental quantity that can be measured is the magnetization, and how it develops with temperature, applied magnetic field and varying sample parameters. Essentially, it is the prerequisite to any other investigations.In this proposal, we request funding to acquire a state-of-the-art SQUID magnetometer. This latest generation of commercial magnetometers has an order of magnitude improved sensitivity, significantly higher data-quality and data-collection rate allowing more and better data to be collected. Moreover, the desired system can be provided with a high-temperature option to 1000K of which there exist only once comparable system in Switzerland, and magneto-optical SQUID magnetometry, which to our knowledge will be unique in Switzerland. Moreover will we develop high-pressure diamond anvils both for low temperature and, using laser heating through the magneto-optic system, up to high temperatures relevant for planetary science. Also these options will be unique in Switzerland.The requested instrument will be installed and maintained in the Laboratory for Quantum Magnetism (LQM), where about 12 PhD students, postdocs and senior scientists will benefit from it for their individual research projects, a selection of which are outlined in section 2. We will operate it as a facility open to collaborators from all of EPFL and the rest of Switzerland. The very wide base of scientists that will benefit from the equipment is documented by the list 20 currently funded projects (SNF, ERC and Innosuisse) that foresee use of the machine. Additionally, the machine will service local Swiss industry both through Innosuisse R&D projects and as a service facility for companies. Examples of such collaborative projects are also provided in section 2.Through the many planned sub-projects, the requested instrument will address the following scientific topics: Novel Magnetic Materials, Unconventional superconductivity, Functional magnets, Magneto-optical materials, High-pressure magnetometry and Industry driven materials science.
