Effect of Doping Elements on Magnetic Properties of Palladium-Based Membrane Alloys

The structural and phase state of palladium-based alloy samples is studied by precision X-ray diffraction using synchrotron radiation (SR). The samples are hydrogenated from the gas phase at 300 С–16 atm. The magnetization of the original and hydrogenated samples is measured in fields up to 1 T in t...

Description
Summary:The structural and phase state of palladium-based alloy samples is studied by precision X-ray diffraction using synchrotron radiation (SR). The samples are hydrogenated from the gas phase at 300 С–16 atm. The magnetization of the original and hydrogenated samples is measured in fields up to 1 T in the temperature range from 77 to 300 K. It is found that all compositions have a small magnetic moment, which varies with temperature and magnetic field. The magnetization of both unhydrogenated and hydrogenated samples in an external increasing magnetic field increases, which is typical for paramagnets. The type of palladium doping element significantly affects the changes in the magnetic susceptibility of membrane alloys.
