The corrosion resistance of iron manganese thin films can be improved considerably without degrading its magnetic properties. To achieve this, iron manganese is alloyed with small amounts of chromium, typically 2 to 5 atomic percent, and subsequently annealed in air or oxygen atmosphere at moderate temperatures between 100 and 200 degrees Celsius for one to two hours. In very thin films of 150 angstrom or less, improved corrosion resistance is already obtained for the iron manganese chromium alloy without the anneal procedure.
