## TL;DR

This paper introduces a synchrotron-based X-ray scattering method that simultaneously probes the magnetic and structural properties of nanopatterned surfaces, enabling detailed correlation of magnetic behavior with surface morphology.

The novel technique combines Grazing Incidence Small Angle X-ray Scattering with Nuclear Resonant Scattering to disentangle magnetic properties in heterogeneous nanostructured systems.

## Key findings

- Demonstrated correlation between structural growth and magnetic evolution.
- Observed magnetization reversal in nanopatterned samples.
- Enabled attribution of magnetic properties to specific structural features.

## Abstract

We present a synchrotron-based X-ray scattering technique which allows disentangling magnetic properties of heterogeneous systems with nanopatterned surfaces. This technique combines the nmrange spatial resolution of surface morphology features provided by Grazing Incidence Small Angle X-ray Scattering and the high sensitivity of Nuclear Resonant Scattering to magnetic order. A single experiment thus allows attributing magnetic properties to structural features of the sample; chemical and structural properties may be correlated analogously. We demonstrate how this technique shows the correlation between structural growth and evolution of magnetic properties for the case of a remarkable magnetization reversal in a structurally and magnetically nanopatterned sample system.
