  We here study electronic structure and magnetic properties of bcc
Co$_{x}$Fe$_{1-x}$, Cr$_{x}$Fe$_{1-x}$ and Mn$_{x}$Fe$_{1-x}$ in their
ferromagnetic phases using Augmented Space Recursion technique coupled with
tight-binding linearized muffin tin orbital (TB-LMTO) method. We make a
systematic study of magnetic properties like magnetic moment and Curie
temperature and try to draw some conclusions on their variation across the row
of 3-{\it d} transition metal series in periodic table using arguments based on
effects like charge transfer, exchange splitting and hybridization.
