Since the late 70ies researchers at ISOLDE-CERN have been applying nuclear techniques to materials science research. A considerable infrastructure has been built up on-site to allow scientists to perform experiments using short-lived isotopes, especially using Time Differential Perturbed Angular Correlations (TDPAC) [1] and Mössbauer Spectroscopy (MS) [2, 3]. The online production of radioactive isotopes with high yield and elemental and isotopic purity allow the choice of the adequate probe to study the relevant solid state problem. In this context, TDPAC and emission MS are very powerful to characterize new materials and particularly atomic defects in them with very small concentrations of nuclear probes. Our facilities at ISOLDE-CERN are the world reference for these measurements. They are dedicated to many different purposes e.g. investigations of semiconductors oxides, photocatalytical materials, multiferroics, superconductors, metals, and alloys. In this presentation, we explore the multiple measurement possibilities.
