Abstract / Bemerkung
Heterogeneous M-Co alloys (M = Cu, Ag, Au) have been observed by transmission electron microscopy (TEM). The magnetic properties and the GMR effect are compared with the evolution of the microstructure after preparation of the samples and after annealing. Limiting effects in TEM that prevent resolving ferromagnetic Coprecipitates in Cu-Co or Ag-Co can be overcome by choosing the system Au-Co. Annealing causes a coarsening of the Co precipitates and an increase in the interparticle distance. Lorentz microscopy confirms single domain Co particles exist in as-quenched Au71.6Co28.4 ribbons, and multidomain Co particles in annealed ribbons, respectively. The changes in the grain size and the formation of multidomain particles can be exactly correlated with magnetic measurements.
