Layered van der Waals materials are widely used in many different research areas. In majority of cases, they are exfoliated flakes that pass only quick test of functional properties without thorough characterization. In this talk, I will present results of detailed investigation of the magnetic, electronic and structural properties of single layers of the Transition Metal DiHalides (TMDH) acquired using various synchrotron- and laboratory-based techniques (LT-STM, XAS/XMCD, ARPES, PEEM/LEEM etc). With a help of these data I will discuss peculiarities of the growth of these materials on various single crystal substrates and a correlation between the magnetic properties of the single-layer TMDH films [1,2] and complex magnetic structures of the bulk TMDH crystals [3].
