The rare earth Neodymium hosts a wide range of multi-Q magnetic phases at temperatures below 20K and fields up to 4T [1]. Recently, Neodymium was found to exhibit a previously unknown spin glass behavior in bulk-like thick films [2]. We study the interplay of magnetism and the electronic structure of bulk single crystal samples grown with the Czochralski method and map the magnetic phase diagram of Nd using vibrating sample magnetometry. First results of Fermi surface study using Shubnikov-de Haas measurements and Density Functional Theory calculations will be presented.
