MAGNETIC SUSCEPTIBILITIES OF PRASEODYMIUM AND TERBIUM OXIDES. Technical Note No. 4
Technical Report
·
OSTI ID:4330922
The magnetic susceptibilities of the three oxides of praseodymium -- Pr/ sub 2/O/sub 3/, Pr/sub 6/O/sub 11/, and PrO/sub 2/ -- and the three oxides of terbium -- Tb/sub 2/O/sub 3/, Tb/sub 4/O/sub 7/, and Tb/sub 6/O/sub 11 / --were measured over a range of temperature. The magnetic moments for the praseodymium oxides are 3.55, 2.77, and 2.51 Bohr magnetons, respectively, while those of the terbium oxides are 9.62, 8.70, and 8.49 Bohr magnetons, respectively. These values are based on temperature-susceptibility data below 300 deg K and indicate adherence to the Curie-Weiss law. They are in good agreement with theoretical values ior the proposed formula. Above 300 deg K the slope for T vs. 1/X/sub M/ changes abruptly and would give considerably lower moments if extrapolated. (auth)
