Abstract
The magnetic susceptibilities of hydrogen doped 4d–3d metallic glasses have been measured in the temperature range from 2K to 300K. It has been found that χ(T) decreases substantially with increasing hydrogen content. This behaviour is primarily attributed to reductions in the density of the Fermi level electronic states. The form and magnitude of the observed anomalous temperature dependence of the magnetic susceptibility ~T⁻¹ᐟ² are in agreement with recent electron interaction theories which predict quantum corrections to the susceptibility. Hydrogen has been found to influence strongly the quantum-mechanical interference at defects, thus slowing down the spin diffusion and enhancing the susceptibility at low temperatures.
