Abstract
By means of the Full Potential LAPW we have done self consistent calculations for FeTi, FeV, FeCr,
FeMn, Fe- bcc and FeCo in the B2 structure, and additionally for Fe- fcc. Isomer shifts
( )
were obtained from electron density calculation in the previously mentioned compounds. These values
are in good agreement with experimental data which are not always available. Structural parameters
as lattice constants and Bulk Modulus, were also calculated. The errors in the parameters calculated
were 1 % or 2 % respect to experimental values.
