A review is given for investigations of the magnetic state of transition element atoms in compounds and alloys using Ka1 spectra. The shift and width of the Ka1 line are used for determining changes in the spin and charge density on the emitting atom depending on the type and concentration of the components. This method permits us to determine the local magnetic moment at an atom with precision of 0.1–0.2 µB. The electron state density in the conductance band affects the spin density formed on the resonance 3d level of an atom in the field of a 2p vacancy. Localization of 3d states was observed upon the transition of an atom to an impurity state. The contribution to the spin state on the emitting atom in Pauli paramagnetics is proportional to the state density on the Fermi level. The width of the Ka1 line of transition element atoms was found to depend on the magnetic moment on the atoms of the immediate environment and on the magnitude and sign of the exchange interaction between them, which permits us to study magnetic phase transitions. |
