Abstract:

The final design and construction of a Weiss-Foex magnetic balance were completed and the balance was adapted to make measurements at low temperatures. The balance was used to measure the paramagnetic susceptibility of a rare earth-transition metal compound and to determine the temperature dependence of the susceptibility. The initial measurements and calibration led to an over-all accuracy of 6.08 in the range of susceptibilities of from 2 to 100 X 0.000001 emugram. Ferrous ammonium sulfate and nickel chloride were used as standards for calibration. The compound YCo2 was investigated and proved to have a paramagnetic moment which followed the Curie-Weiss Law. The Curie constant was found to be .19 X 0.000001 emu-K gram and the Weiss constant was found to be 53 K. Author
