Electronic and magnetic properties of the inverse magnetoresistant Fe1-xCoxSi alloys

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...
