Role of Dirac cones in magnetotransport properties of REFeAsO (RE=rare earth) oxypnictides

, 2013
In this work we study the effect of the rare earth element in iron oxypnictides of composition REFeAsO (RE=rare earth). On one hand we carry out Density Functional Theory calculations of the band structure, which evidence the multiband character of these
