Magnetism of nanostructures is often studied by means of x-ray magnetic circular dichroism (XMCD). The XMCD sum rules are a very powerful tool but they allow for the spin magnetic moment μspin to be determined only in combination with the magnetic dipole term Tz. This chapter presents few examples demonstrating that neglecting Tz could in some cases lead to completely wrong conclusions about the trends of μspin with the size of the system or with the magnetisation direction. Further, we inspect conditions that have to be met so that eliminating of Tz from the XMCD sum rules is possible.
