Magnetic Susceptibility of Close-Packed Hexagonal Gold-Indium Alloys

Abstract
The magnetic susceptibility of close-packed hexagonal gold-indium alloys has been measured at 300°K, 77°K, 4.2°K, and 1.2°K. The susceptibility data show a striking similarity to the c-axis spacing, exhibiting a maximum at about 19 at.% In, consistent with a model assuming that the Fermi surfaces touch the Brillouin zone face (0002) at this concentration.
