Magnetic Properties of Plutonium Hydride and Deuteride

Abstract
Magnetic investigations on plutonium hydride (PuH2.74) and deuteride (PuD2.74) have shown these compounds to be either ferromagnetic, like the corresponding uranium compounds, or ferrimagnetic. The Curie temperatures of plutonium hydride and deuteride are the same, within experimental error, and are 107°K. The magnetic moment for the hydride and deuteride are greater than 0.24 and 0.13 Bohr magnetons per mole of compound, respectively, at 76°K. In addition the cubic plutonium oxide PuO1.62 was found to be either ferro‐ or ferrimagnetic with a magnetic moment greater than 0.16 Bohr magnetons per mole of plutonium at 4°K and a Curie temperature of 96.7°K.
