  The Augmented Space Formalism coupled with Recursion method and Density
Functional Theory based Tight-Binding Linear Muffin-Tin Orbitals have been
applied for a first principles calculation of surface electronic and magnetic
properties of body centered cubic Fe(001) and face centered cubic Co(001) and
Ni(001). Nine atomic layers have been studied to see the trend of change in
these properties from surface into the bulk. Surface magnetic moment has been
found to be higher than that of the bulk and in different layers below,
magnetic moments show Friedel oscillations in agreement with other studies.
Work functions of these systems have been found to agree with experimental
values. We propose this real space technique to be suitable for the study of
localized physical properties like surface layers and it is also suitable for
the study rough surfaces and interfaces.
