Hydrogen-induced changes in magnetic susceptibility of(Zr68Fe32)1<

Effect of disorder on the electrical resistivity in the partially crystalline Zr76Ni24 metallic glasses

“…The increase in the T c upon annealing up to an annealing temperature below the first crystallisation exotherm in the Zr 80 Fe 20 and Zr 80 Co 20 metallic glasses has been related to the decrease in the spin-fluctuation mass enhancement parameter, λ sp . It is well known that the influence of spin fluctuations on superconductivity in Zr-3d metallic glasses decreases with increasing Zr concentration whereas at fixed Zr concentration it decreases as one move from Fe towards Ni [13,[24][25][26]. Thus, the effect of the λ sp on superconductivity in the investigated samples can be negligible.…”

The magnetic susceptibility of hydrogen-doped partially crystalline (Zr76Ni24)1−xHx metallic glasses

“…Hydrogenation was carried out electrolytically using the sample as a cathode and a platinum wire as an anode. The dopant concentrations were determined volumetrically [13]. The samples were subjected to an analysis of crystallisation characteristics using differential scanning calorimetry and electrical resistivity measurements.…”

Influence of hydrogen doping on the electrical resistivity of partially crystalline Zr76Ni24 metallic glass

“…The hydrogenation was carried out electrolitically using the sample as a cathode and a platinum wire as an anode. The dopant concentrations were determined volumetrically [16]. The structures of the samples before and after the hydrogenation were investigated at a room-temperature by XRD using a PHILIPS PW 1820 diffract meter with Cu K␣ radiation [5,17].…”
