Giant magnetoresistance and anomalous Hall effect in Co-Ag and Fe-Cu, Ag, Au, Pt granular alloys

Magnetotransport and magnetic properties are studied in Co-Ag and Fe-Cu, Ag, Au, Pt alloys. In every system except Fe-Pt, giant magnetoresistance (GMR) is observed. The GMR effect is characterized as the volume fraction of the magnetic particles and the particle size are varied. Anomalous Hall effects are observed, and other transport parameters obtained in these systems are presented.<
