(a) Plane view HRTEM image of a cluster embedded inside the GeMn matrix. (b) EELS measurements performed along the line where cross marks indicate probe positions for specific spectra. (c) EDS spectrum obtained for regions free of clusters. (d) EDS spectrum obtained for regions containing clusters.

FIG. 3.

Temperature dependence of the magnetic parameters measured by magneto-optic Kerr effect for the films: (a) remanence and (b) coercive field. The lines in (a) and (b) are the fitting curves following a relation of the form , with and 1, respectively. (c) Hall coefficient of layers as a function of temperature. The symbols refer to different values of : (squares) ; (circles) ; and (triangles) (for more details on the magnetic and electrical results, see Ref. 9).
