Abstract
The Hall effect in amorphous Pd80Si20 and Pd80−x Si20Co x , wherex=2, 4, 6 (at.% are implied throughout) alloys was investigated. Measurements were carried out at r.t. in fields up to 17·5 kG. Also the electrical conductivityσ was measured. The Hall effect was found negative in all alloys of the above composition. Observedx-dependence of the Hall constantR H tends to change the sign of the effect and is interpreted on the assumption that an extraordinary Hall effect manifests itself besides the ordinary one in Co-containing alloys. The value ofR H for the basal alloy should be looked upon as an evidence of electron transfer from glass-former (Si) to transition metal (Pd) empty d-states. The values ofR H obtained for the alloys withx=0, 2, 4, 6 are respectively, −7·8; −8·7; −8·3; −5·2 (×10−5 cm3/A. sec throughout).
