Abstract
We present a theoretical study of the magnetic properties at finite temperature of the ideal (100) surface of iron. The spin-polarized electronic structure at a given temperature is determined with a self-consistent d-band model Hamiltonian in which correlation effects are included in a temperature-dependent splitting parameter. The demagnetization process is analyzed and compared with previous results and experimental trends, which will serve us as a test. The applicability of the model to the study of other complex systems like supported clusters or surfaces with defects is discussed.
