Structural, electronic and magnetic properties of YMnO₃/La_0.7Sr_0.3MnO₃ heterostructures

Using polarized neutron reflectometry, the magnetic proximity effect in epitaxial bilayer heterostructures comprising ferromagnetic La_0.7Sr_0.3MnO₃ and multiferroic orthorhombic YMnO₃ layers has been investigated.

Self-organization of Fe clusters on mesoporous TiO₂ templates

The growth of Fe on a mesoporous structure of titania anatase template has been investigated. The lateral and longitudinal correlation of the Fe layers as a function of thickness demonstrate the impact of the deposition kinetics on the physical properties of supported islands in the nanometric regime. Three different stages of growth were identified, characterized by different correlation lengths and magnetic behaviors in each regime.
