The field of spintronic has become a flourishing synonym of dense, ultra-fast, persistent and especially low-power future information technologies with fantastic promises ranging from replacement of CMOS techniques to impacts in quantum computing. New lines came up as magnonics, spin-orbitronics, antiferromagnetic spintronics, skyrmionics and multiferroics including topological aspects appearing in novel graphene-like and van-der-Waals systems. However, the impact on the real market is nowadays rather limited, since the serious drawbacks are present not only from the technological site but even from fundamental aspects. Also, the theoretical and simulation approaches are strongly hampered by unknown and often wrong input parameters. This talk presents our attempts to get realistic, robust information on the crucial magnetic values as saturation, exchange constants, anisotropy, temperature behavior in reduced dimensions as well as their spatial and time evolution. Therefore, we combine careful SQUID, MOKE and x-ray techniques on identical or comparable samples.
