Anomalous Magnetoresistance in Al/Al-Alloy Composite Conductors
Abstract The transverse magnetoresistance of several composite conductors containing a large single filament of pure aluminum in a matrix of Al-Fe-Ce has been measured at 4 K to fields of 10 T. The magnetoresistance (ΔR/R) of the composite is very large, rising to 55 in the “worst” case. Previous measurements on pure polycrystalline aluminum have always shown a rapidly saturating behavior with a very small linear component; AR/R rarely exceeds a value of 5–6. In addition, the magnetoresistance of the composite samples shows a structure as the field is rotatated around the current axis.
