Sažetak
The magnetisation of hydrogen-doped (Zr80Co20)1-xHx metallic glasses has been measured in the temperature range 1.7 K -100 K for various dopant concentrations. The system is paramagnetic and becomes superconducting at Tc = 3.98 K. The magnetic susceptibility of the undoped sample above Tc is strongly temperature dependent and shows the Curie-Weiss behaviour whereas in the doped samples it is temperature independent. It has been also found that the magnetic susceptibility at 100 K, (100 K), decreases with hydrogen concentration. The low-temperature upturn in the undoped sample most likely results from a small amount of magnetic impurities. Doping the sample with small hydrogen concentration results in the screening of magnetic impurities thus reducing the Curie-Weiss contribution to the magnetic susceptibility. The form and magnitude of the observed temperature dependence of the magnetic susceptibility are well accounted for by the sum of the Curie-Weiss term and the quantum corrections to the susceptibility.
