<p>  Exchange coupling field Hex was found to increase with time when MnIr/CoCr exchange coupling films were left at room temperature in air. The exchange field Hex of samples prepared with the substrate heated up to 50°C or 100°C was greatly reduced. In addition, while the exchange field Hex of the sample deposited at the substrate temperature of 50°C increased with time, it did not increase when the sample was deposited at the substrate temperature of 100°C. TOF-SIMS data taken from samples immediately after deposition, after Hex was saturated, and after deposition at the substrate temperature of 100°C showed that the element profiles were quite similar, except for a decrease of Mn composition at the MnIr/CoCr interface in the sample deposited at the substrate temperature of 100°C. From these results, a model is proposed to explain what causes the increase of Hex by Mn diffusion. It was found that the direction of the field when the sample was left at room temperature after deposition had a great effect on the resultant Hex. No change in crystal structure was observed, indicating that the time dependence of Hex was caused by a change in the magnetic structure.</p>
