Temperature dependence of the magnetization of transition-metal thin films: Fe-monolayers and bilayers Article uri icon

abstract

  • The functional integral theory of bulk itinerant magnetism is extended to be applied to low-dimensional transition-metal systems. Using a real-space recursive expansion of the local Green%27s function we calculate the magnetization curves and the Curie temperature T C for the bulk, monolayer, and bilayer of Fe. Disorder is treated by using the virtual crystal approximation. The local-environment dependence of T C is analyzed by comparing the results for bulk and the (001) and (110) oriented films of Fe. Finally, the applicability of the theory is discussed. © 2002 American Institute of Physics.
