摘要: Abstract High-field magnetization curves are presented for AuFe alloys of Fe concentrations: c = 3.1, 5.1, 6.5 and 10.4 at.%, at T 4.2 K in pulsed fields up to 40 T. For at.% additional data were taken 1.2 77 K. From these results we conclude that the nearest-neighbour interaction between atoms Au is ferromagnetic, order 80 The behaviour can be qualitatively explained terms ferromagnetic clusters antiferromagnetically coupled.
