Vector-simulated magnetism of Fe/V nanostructures

The self-consistent calculations of magnetic moments distribution for the ordered and disordered Fe/V alloys are performed in the framework of vector periodic Anderson model. The calculations of magnetization for disordered alloys are in a good agreement with the experiments in the whole concentration range. It is shown that the ordered FeV equiatomic structure of CsCl-type as well as small paramagnetically ordered Fe clusters in the V surroundings cause a dramatic decrease of the magnetization.
