Abstract
We have studied the Hall effect in amorphous paramagnetic ZrxCo100−x alloys, with 48 ⩽ x ⩽ 80, between 1.5 and 300 K. In these alloys RH shows a very small temperature dependence but a large variation with concentration, being negative in the high cobalt region and positive on the zirconium-rich side. This behaviour, which has also been found in other zirconium-based glasses, cannot be explained classically. By comparison with the ZrFe system we propose that a significant contribution to RH via the side-jump mechanism, as proposed by Berger, has to be considered when trying to explain the behaviour of RH in these ZrCo metallic glasses.
