Resumen:
The alloy Fe1-xCoxSi shows a remarkable behaviour, while the two extremes are both nonmagnetic almost all the intermediates show magnetic order, specially in the Fe-rich region. We present here ab initio calculations within the LSDA approximation for these compounds and show that they behave as half metals for xp0:25: This explains the linear dependence on x of the magnetic moment in this region. We also explain the magnetic behaviour for largerconcentrations.
