Magnetic behaviour ofCuAuFe alloys
Tóm tắt
The magnetic properties of Cu99-xAuxFe1 alloys (x=12, 37 and 50.7 ats) have been investigated over the temperature range ∼4.2–70 K using low field AC magnetic susceptibility measurements and mössbauer spectroscopy. All alloys exhibit spin glass behaviour at low temperature with freezing temperatures Tf∼-5.7–7.6 K. Results of analysis of the high temperature (T≳3 Tf) Curie-Weiss behaviour are compared with those obtained from analysis of the broadly distributed 4.2 K Mössbauer spectra.
