High-quality single crystals are an important prerequisite for major advances in experimental solid-state research. To ensure high degree of structural order with a small crystalline mosaicity, low concentrations of defects and impurities, and the absence of parasitic phases, it is crucial to avoid contaminations in every step of the preparation process [1]. The central part of our preparation process is the optical floating zone technique. After moving to a new laboratory, we have re-established our ultra-high vacuum compatible preparation chain for intermetallic compounds and demonstrated its potential by preparing samples from several compound, such as the potentially frustrated paramagnet Fe2Al5 [2].
