Abstract: | Values of the low temperature specific heat of f.c.c. Ni-Co and Ni-Fe alloys have been determined in the 1.2–8 K range with a relative accuracy of 10-3 and analysed to separate the electron, phonon, magnon and hyperfine terms. Results are in good agreement with former data5–7 and with theory: Gomes' model4 of a d-d tight-binding scattering in the dilute case, Hasegawa's12,13 CPA calculations are both consistent with experiments. |
