Abstract

Magnetic percolation has rarely been realized in Fe-based binary alloys either because Fe does not retain its moment in the dilute limit or because the solubility is too low. By using a vapor quenching method, which in our case is high-rate sputtering, authors have succeeded in making new metastable crystalline alloys of fcc Fe//xCu//1// minus //x which do not appear in the equilibrium phase diagram. These alloys spanning the percolation threshold allow magnetic percolation phenomena on an fcc lattice to be observed by SQUID magnetometry and Moessbauer spectroscopy. Above x//c, the magnetic ordering temperature varies as (X minus x//c)** gamma with x//c equals 0. 185 and gamma equals 0. 63. Below x//c, spin glass ordering has been observed.
