Mn and Fe Impurities in MgB_{2}
arXiv:cond-mat/0512675 · doi:10.1016/j.ssc.2006.11.025
Abstract
Based on first principles calculations, we show that impurities are magnetic in due to exchange-splitting of band and they substantially modify and bands through hybridization. Thus, impurities could act as strong magnetic scattering centers leading to pair-breaking effects in . In contrast, we find impurities in to be nearly non-magnetic.
