Magnetic-moment formation of Fe and Mn in crystalline and amorphous Ga: Anin situlow-temperature ion-implantation study

Abstract
Low-temperature (Ta-) Ga films. Because of their restricted stability (a-Gain situ. Using the concentration dependence of the superconducting transition temperature as a probe for the magnetic behavior it is found that only Mn forms a long-lived magnetic moment in both Ga modifications, while the results for Fe are consistent with a rapidly fluctuating short-lived moment.
