X-ray absorption spectroscopy study of the electronic and magnetic proximity effects in YBa2Cu3O7/La2/3Ca1/3MnO3 and La2-xSrxCuO4/La2/3Ca1/3MnO3 multilayers

Popis výsledku v původním jazyce

With x-ray absorption spectroscopy we investigated the orbital reconstruction and the induced ferromagnetic moment of the interfacial Cu atoms in YBa2Cu3O7/La2/3Ca1/3MnO3 (YBCO/LCMO) and La2-xSrxCuO4/La2/3Ca1/3MnO3 (LSCO/LCMO) multilayers. We demonstratethat these electronic and magnetic proximity effects are coupled and are common to these cuprate/manganite multilayers. Moreover, we show that they are closely linked to a specific interface termination with a direct Cu-O-Mn bond. We furthermore show that the intrinsic hole doping of the cuprate layers and the local strain due to the lattice mismatch between the cuprate and manganite layers are not of primary importance. These findings underline the central role of the covalent bonding at the cuprate/manganite interface in defining the spin-electronic properties.
