MAGNETIC SUSCEPTIBILITY OF THE TWO PHASES OF LITHIUM AT LOW TEMPERATURES
The Curie method was used to determine the susceptibility of the high- purity lithium samples which were in the form of bare rods. The absolute room temperature susceptibility of the samples was from (1.89 + 0.01) x 10/sup -6/ to (1.93 plus or minus 0.01) x 10/sup -6/ emu/g and is in reasonable agreement with the value reported by Pugh and Goloman. The temperature dependence of the susceptibility above the phase transformation region (150 to 300 deg K) showed a slight T/sup -1/ paramagnetism which indicates paramagnetic impurities in solution. Susceptibility measurements of various samples are tabulated as a function of temperature. Measurements are being continued at higher magnetic fields and attempts are currently being made to reduce the ferrous content of the available lithium samples. Measurements on high-purity distilled sodium are being made where the difficulties of preparing ferrous free samples are not as great as for lithium. (B.O.G.)
