Neutron reflectometer with horizontal scattering geometry

Magnetic domains and off-specular scattering

D17 in TOF-polarised mode is well-adapted for measurements of magnetic samples.

The wide angle coverage of the multidetector allows the detection of magnetic off-specular scattering simultaneously to the specular reflectivity. 

In this example, the magnetic scattering from a 5 μm domain pattern in head-to-head configuration was investigated to resolve details of the domain structure and internal magnetizations.
