A previously proposed symmetrized method for the calculation of the electronic structure of spiral magnetic configurations is employed in the study of non‐collinear magnetic configurations of iron and nickel. It is shown that there is a marked difference of the tendencies of changes in the electronic structure of both metals being studied due to the increase of the angle between the spins of neighbouring atoms. A qualitative interpretation of the observed changes is given in terms of a simple two‐band model. It is also shown that the difference in the behaviour of the electronic structure of both, iron and nickel leads to a substantially different behaviour of a self‐consistent local magnetic moment and total electronic energy as a function of the angle between the spins of the neighbouring atoms.
