note = "Funding Information: We have investigated the magnetoresistance of the metallic compound AuA12 in fields up to 140 kG. The samples were sufficiently pure \[p(295°K)/p(4.2°K) = 400 550\] that the high-field condition was satisfied. We compare our experimental results with those predicted by a computer analysis of the MR expected from a nearly free electron model. In general there is qualitative agreement with one notable exception. Preliminary work on AuGa 2 and AuIn 2 crystals with resistance ratios of 200 and 60, respectively, is also consistent with the magnetoresistance properties of a nearly free electron model. All three compounds crystallize in the f.c.c. fluorite structure with three atoms per primitive cell. The nearly free electron Fermi surfaces, assuming seven nearly free electrons per primitive cell, are shown in a paper by Jan et al. \[1\], who investigated these compounds with the de Haas-van Alphen effect. We have analyzed the nearly free electron surfaces with the aid of a computer program which gives the direction of open orbits and the thickness of the band of open orbits, measured parallel to B. The analysis indicates that the 4111) directed necks in the third zone hole surface support primary open orbits along 41115 directions and secondary open orbits along 41005 and 4110) directions. The 41005 directed arms of the fourth zone electron sur- * This work was performed in part at the National Magnet Laboratory which is supported by the U.S.A.F.O.S.R. ** Supported by the National Science Foundation. *** Supported by the Advanced Research Projects Agency.",
