Magnetic and electrical properties of Co-rich cobalt-iron films

The crystalline structures and galvanomagnetic properties have been studied on Co-Fe films of 80–100% Co. It is found that in single- to multiphase transition region the structure of this alloy system is characterised by the minimum electron number per atom. Moreover, the variations in such magnetic parameters as the anomalous Hall constant and saturation induction do not follow the simple mixing rule, but depend on a crystal structure type of the alloy.
