The researchers of the unit are users of large scientific infrastructures: European Synchrotron Radiation Facility; ISIS Synchrotron at STFC Rutherford Appleton Laboratory BESSY synchrotron; ILL neutron reactor. Advanced Photons Source (Argonne Nat. Lab); Oak Ridge National Laboratory Center for Nanophase Materials Science; Los Alamos Neutron Science Center.
 
In addition, UCM has several facilities that complement the above experimental techniques. It is worth mentioning the X-Ray Diffraction service which provides solutions for powder, single crystal and thin film diffraction based on a well- equipped set of diffractometers.
 
The researchers of the unit use calculation and simulation facilities, being the most relevant one CeSViMa, the center for computation and simulation of Comunidad de Madrid which hosts the supercomputer Magerit 2. It is used by members of the proposed Maria de Maeztu unit that perform simulations of magnetic materials for quantum computation and simulations. CeSViMa belongs to RES comprising 7 centers
