High field magnetoresistance of orientedcrystallites of AuPb2

High field magnetoresistance measurements have been made on samples of AuPb₂, which consist of islands of oriented AuPb₂ surrounded by eutectic mixture. The results obtained are very similar to what would be expected for single crystal samples. Open orbits are observed in 〈100〉, 〈110〉, 〈101〉, 〈112〉 and 〈211〉 and 001] directions. The results are consistent with predictions of the Nearly Free Electron Model.
