Proposal of an empirical formula for the relation between temperature and concentration of Fe impurities in Au Fe spin-glass alloy

According to importance of the use of nano-dimensions in modern experimental techniques, a lot of studies on the thermal transition investigations on Au Fe spin glass alloys has been carried out. The studied alloys has spectrum of the magnetic impurity in concentration range (0.1% - 15%), and temperature range (0.01-300 degree k). Because there is no one source that can give all exact experimental information, we got the experimental data (resistivity, specific heat, susceptibility, Moessbauer effect , neutron scattering, magnetization and hysteresis cycles, NMR , SR), from many sources and obtained a new theoretical and experimental thermal magnetic phase diagram. An empirical formulae for the relation between temperature and concentration has been suggested.
