                                ABSTRACT

I will discuss some general aspects of structural and magnetic correlations 
that can be accessed by various neutron and x-ray scattering techniques at low 
angle. Among several emergent systems investigated, I will focus on an 
exchanged coupled prototypical system under various conditions of field 
cooling. Some important correlations aspects will also be discussed with 
respect to non-magnetic nano-structures of different dimensions. I will 
introduce the case of topologically stabilized spin configurations like helices 
in the form of planar domain walls with magnetic functionalities in transition 
metal/rare-earth systems. Realization of such spin configurations opens up the 
opportunity for scientific and technological applications in increasing the 
energy density for all-spin-based systems. Finally, important correlations 
aspects will also be discussed with respect to rare-earth/rare-earth systems 
where we predict the existence of magnetic vortex-like domains associated with 
magnetic helical ordering within the layers.
