|Title:||La Doping Effects In The Coupling Between Localized And Itinerant Electronic States In Eufe2as2 Probed By Eu2+ Esr|
|Abstract:||In this work we present an Electron Spin Resonance (ESR) study on La-doped EuFe2As2 aiming to further understand the coupling of localized spin states and itinerant electrons in these systems. The temperature dependence of the Eu2+ ESR linewidth, g-value and intensity was investigated for both monocrystalline and powdered samples. Our results confirm the suggestion of previous ESR experiments on the pure compound , that the SDW transition dramatically changes the coupling between localized and itinerant states. In addition, we found a peculiar dome like shape in the Eu2+ ESR linewidth temperature dependence for temperatures between TSDW and TN. © Published under licence by IOP Publishing Ltd.|
