Neutron spin tomography. A tool to visualize magnetic domains in bulk materials

The possibility of a visualization of magnetic domains in bulk materials by the recently proposed tomographic neutron depolarization technique is discussed. In particular a numerical procedure is presented which allows the analysis of tomographic tensorial data taking into account the non-Abelian character of the involved tensors in lowest order. Analyzing schematic data sets it is shown that in principle it is possible to reveal the inner magnetization by tomographic neutron depolarization measurements. (author)
