作者测量了含20-53 at.%的Au的磁化强度、电阻、霍尔效应和横向磁电阻镍在淬火和长期老化状态。在大约2- 300 K下，在高达21 kOe的磁场中测量磁化强度，并在高达60 kOe的磁场中测量电性能。退火状态被解释为是一个混合物的相干沉淀，一个富Ni和其他富Au。淬冷态较难淬冷，可能是与团簇玻璃共存的弱铁磁性。
The authors have measured the magnetisation, electrical resistances, Hall effect and transverse magnetoresistance in Au containing 20-53 at.% Ni in both a quenched and a longterm aged state. Measurements were made at approximately 2-300K in fields of up to 21 kOe for the magnetisation and up to 60 kOe for the electrical properties. The annealed state is interpreted as being a mixture of coherent precipitates, one Ni-rich and the other Au-rich. The quenched state, which is more difficult to characterise, is probably weak ferromagnetism coexisting with a cluster glass.
