摘要：

A calculation scheme is discussed that permits the investigation of both transverse and longitudinal fluctuations of local magnetization in 3d magnets. It is based on the use of a band-structure calculation method for the study of excited magnetic states. Calculations were carried out for body-centred cubic Fe and face-centred cubic Ni. The probability distribution of the local magnetic moment length is evaluated for the paramagnetic region. Some comparisons are made, illustrating the role of longitudinal fluctuations as well as the role of electronic characteristics of excited states.
