| Abstract: | An57Fe Mössbauer study and60Co and54Mn nuclear orientation (NO) studies of the Au86Fe14 alloy have been performed. A transition to the spin glass state was observed below approximately 50 K. NO of the60Co impurity showed absence of the polarization of the60Co nuclei. For54Mn impurities the dependence of the Mn effective magnetic field on external field andtemperature was found. |
