Measurements of magnetization as a function of temperature were performed from 1.8 to 300 K in a 5000-G applied field as indicated. Powder samples were cooled in zero applied field and measured upon warming. Diamagnetic corrections were estimated based on Pascal's constants. Samples are presumed to be fully desolvated, as indicated by elemental analysis.
