| Abstract Scope |
A prevailing model of Pu invokes a spin and orbital cancellation model to predict structural evolution. The hallmark of this spin/orbit cancellation model is the presence of anti-parallel, on-atom spin and orbital moments of identical magnitude (or nearly so) near 3 Bohr magnetons each. Such an offsetting magnetic configuration would be nearly invisible to bulk probes that see only the total moment but x-ray magnetic circular dichroism (XMCD) can offer a glimpse into the local, atomic magnetic configuration. Herein, we will discuss the results of dichroism measurements at the M4 and M5 edges of Ga-stabilized d-Pu acquired at a temperature of 2 K and in magnetic fields up to 60 kOe.
