Abstract
A magnetic balance using the Faraday method and quartz helical springs is described. The susceptibility of the Palladium hydrogen system is investigated within the temperature range from 50 °C to 100 °C. Hydrogen absorption and desorption of a Palladium black sample are caused by varying the hydrogen pressure. The susceptibility and the weight of the sample are observed continuously and fairly near to the equilibrium PdHn/H2 as a function of pressure. The p (n) -isotherms show the well known hysteresis; on the other hand, the χ (n) -isotherms for absorption and desorption coincide and there is no hysteresis. The χ- n relationship is independent of the a→β phase transition. Finally, the results of the susceptibility measurements are compared with the band structure of Pd determined by Hoare and Yates.Keywords
